#### SSE-C encryption (since Garage v1.0)
|
||||
|
||||
Since version 1.0, Garage supports server-side encryption with customer keys
|
||||
(SSE-C). In this mode, Garage is responsible for encrypting and decrypting
|
||||
objects, but it does not store the encryption key itself. The encryption key
|
||||
should be provided by Nextcloud upon each request. This mode of operation is
|
||||
supported by Nextcloud and it has successfully been tested together with
|
||||
Garage.
|
||||
|
||||
To enable SSE-C encryption:
|
||||
|
||||
1. Make sure your Garage server is accessible via SSL through a reverse proxy
|
||||
such as Nginx, and that it is using a valid public certificate (Nextcloud
|
||||
might be able to connect to an S3 server that is using a self-signed
|
||||
certificate, but you will lose many hours while trying, so don't).
|
||||
Configure values for `use_ssl` and `port` accordingly in your `config.php`
|
||||
file.
|
||||
|
||||
2. Generate an encryption key using the following command:
|
||||
|
||||
```
|
||||
openssl rand -base64 32
|
||||
```
|
||||
|
||||
Make sure to keep this key **secret**!
|
||||
|
||||
3. Add the encryption key in your `config.php` file as follows:
|
||||
|
||||
|
||||
```php
|
||||
<?php
|
||||
$CONFIG = array(
|
||||
'objectstore' => [
|
||||
'class' => '\\OC\\Files\\ObjectStore\\S3',
|
||||
'arguments' => [
|
||||
...
|
||||
'sse_c_key' => 'exampleencryptionkeyLbU+5fKYQcVoqnn+RaIOXgo=',
|
||||
...
|
||||
],
|
||||
],
|
||||
```
|
||||
|
||||
Nextcloud will now make Garage encrypt files at rest in the storage bucket.
|
||||
These files will not be readable by an S3 client that has credentials to the
|
||||
bucket but doesn't also know the secret encryption key.
|
||||
|
||||
|
||||
### External Storage
|
||||

||||

As such, your Garage cluster should be configured appropriately for good performance:

|
||||
- use Garage v0.8.0 or higher with the [LMDB database engine](@documentation/reference-manual/configuration.md#db-engine-since-v0-8-0).
|

Older versions of Garage used the Sled database engine which had issues, such as databases quickly ending up taking tens of GB of disk space.

With the default Sled database engine, your database could quickly end up taking tens of GB of disk space.

Adding TLS support built into Garage is not currently planned.

## Garage stores data in plain text on the filesystem or encrypted using customer keys (SSE-C)
|
||||
## Garage stores data in plain text on the filesystem
|
||||
|
||||
For standard S3 API requests, Garage does not encrypt data at rest by itself.
|
||||
For the most generic at rest encryption of data, we recommend setting up your
|
||||
storage partitions on encrypted LUKS devices.
|
||||
Garage does not handle data encryption at rest by itself, and instead delegates
|
||||
to the user to add encryption, either at the storage layer (LUKS, etc) or on
|
||||
the client side (or both). There are no current plans to add data encryption
|
||||
directly in Garage.
|
||||
|
||||
If you are developping your own client software that makes use of S3 storage,
|
||||
we recommend implementing data encryption directly on the client side and never
|
||||
transmitting plaintext data to Garage. This makes it easy to use an external
|
||||
untrusted storage provider if necessary.
|
||||
|
||||
Garage does support [SSE-C
|
||||
encryption](https://docs.aws.amazon.com/AmazonS3/latest/userguide/ServerSideEncryptionCustomerKeys.html),
|
||||
an encryption mode of Amazon S3 where data is encrypted at rest using
|
||||
encryption keys given by the client. The encryption keys are passed to the
|
||||
server in a header in each request, to encrypt or decrypt data at the moment of
|
||||
reading or writing. The server discards the key as soon as it has finished
|
||||
using it for the request. This mode allows the data to be encrypted at rest by
|
||||
Garage itself, but it requires support in the client software. It is also not
|
||||
adapted to a model where the server is not trusted or assumed to be
|
||||
compromised, as the server can easily know the encryption keys. Note however
|
||||
that when using SSE-C encryption, the only Garage node that knows the
|
||||
encryption key passed in a given request is the node to which the request is
|
||||
directed (which can be a gateway node), so it is easy to have untrusted nodes
|
||||
in the cluster as long as S3 API requests containing SSE-C encryption keys are
|
||||
not directed to them.

Implementing automatic data encryption directly in Garage without client-side

|
||||
could make things simpler for end users that don't want to setup LUKS, but also
|
||||
raises many more questions, especially around key management: for encryption of
|
||||
data, where could Garage get the encryption keys from? If we encrypt data but
|
||||
keep the keys in a plaintext file next to them, it's useless. We probably don't
|

want to have to manage secrets in Garage as it would be very hard to do in a

secure way. At the time of speaking, there are no plans to implement this in

Garage.

small metadata items, and a data directory to store data blocks of uploaded objects.

|
|||
EXT4 is not recommended as it has more strict limitations on the number of inodes,
|
||||
which might cause issues with Garage when large numbers of objects are stored.
|
||||
|
||||
- Servers with multiple HDDs are supported natively by Garage without resorting
|
||||
to RAID, see [our dedicated documentation page](@/documentation/operations/multi-hdd.md).
|
||||
- If you only have an HDD and no SSD, it's fine to put your metadata alongside the data
|
||||
on the same drive. Having lots of RAM for your kernel to cache the metadata will
|
||||
help a lot with performance. Make sure to use the LMDB database engine,
|
||||
instead of Sled, which suffers from quite bad performance degradation on HDDs.
|
||||
Sled is still the default for legacy reasons, but is not recommended anymore.
|
||||
|
||||
- For the metadata storage, Garage does not do checksumming and integrity
|
||||
verification on its own, so it is better to use a robust filesystem such as
|
||||
BTRFS or ZFS. Users have reported that when using the LMDB database engine
|
||||
(the default), database files have a tendency of becoming corrupted after an
|
||||
unclean shutdown (e.g. a power outage), so you should take regular snapshots
|
||||
to be able to recover from such a situation. This can be done using Garage's
|
||||
built-in automatic snapshotting (since v0.9.4), or by using filesystem level
|
||||
snapshots. If you cannot do so, you might want to switch to Sqlite which is
|
||||
more robust.
|
||||
verification on its own. If you are afraid of bitrot/data corruption,
|
||||
put your metadata directory on a ZFS or BTRFS partition. Otherwise, just use regular
|
||||
EXT4 or XFS.
|
||||
|
||||
- LMDB is the fastest and most tested database engine, but it has the following
|
||||
weaknesses: 1/ data files are not architecture-independent, you cannot simply
|
||||
move a Garage metadata directory between nodes running different architectures,
|
||||
and 2/ LMDB is not suited for 32-bit platforms. Sqlite is a viable alternative
|
||||
if any of these are of concern.
|
||||
|
||||
- If you only have an HDD and no SSD, it's fine to put your metadata alongside
|
||||
the data on the same drive, but then consider your filesystem choice wisely
|
||||
(see above). Having lots of RAM for your kernel to cache the metadata will
|
||||
help a lot with performance. The default LMDB database engine is the most
|
||||
tested and has good performance.

|

Garage needs to know the storage capacity (disk space) it can/should use on

|
||||
Garage reasons on an abstract metric about disk storage that is named the *capacity* of a node.
|
||||
The capacity configured in Garage must be proportional to the disk space dedicated to the node.
|
||||
|
||||
Capacity values are expressed in bytes and are passed to Garage using the `-c` flag of `garage layout assign` (see below).

Capacity values must be **integers** but can be given any signification.

Tags have no specific meaning for Garage and can be used at your convenience.
|
||||
Note that the amount of data stored by Garage on each server may not be strictly proportional to
|
||||
its capacity value, as Garage will priorize having 3 copies of data in different zones,
|
||||
even if this means that capacities will not be strictly respected. For example in our above examples,
|
||||
nodes Earth and Mars will always store a copy of everything each, and the third copy will

have 66% chance of being stored by Venus and 33% chance of being stored by Mercury.

```

*Note that you need the signing key. In our case, it is stored as a secret in Drone.*

The previous command will only send the built package and not its dependencies.
|
||||
In the case of our CI pipeline, we want to cache all intermediate build steps
|
||||
as well. This can be done using this quite involved command (here as an example
|
||||
for the `pkgs.amd64.relase` package):
|
||||
The previous command will only send the built packet and not its dependencies.
|
||||
To send its dependency, a tool named `nix-copy-closure` has been created but it is not compatible with the S3 protocol.
|
||||
|
||||
Instead, you can use the following commands to list all the runtime dependencies:
|
||||
|
||||
```bash
|
||||
nix copy -j8 \
|
||||
--to 's3://nix?endpoint=garage.deuxfleurs.fr®ion=garage&secret-key=/etc/nix/nix-signing-key.sec' \

$(nix path-info pkgs.amd64.release --file default.nix --derivation --recursive | sed 's/\.drv$/.drv^*/')

||||
nix copy \
|
||||
--to 's3://nix?endpoint=garage.deuxfleurs.fr®ion=garage&secret-key=/etc/nix/signing-key.sec' \
|
||||
$(nix-store -qR result/)
|
||||
```
|
||||
|
||||
This command will simultaneously build all of the required Nix paths (using at
|
||||
most 8 parallel Nix builder jobs) and send the resulting objects to the cache.
|
||||
*We could also write this expression with xargs but this tool is not available in our container.*
|
||||
|
||||
This can be run for all the Garage packages we build using the following command:
|
||||
But in certain cases, we want to cache compile time dependencies also.
|
||||
For example, the Nix project does not provide binaries for cross compiling to i686 and thus we need to compile gcc on our own.
|
||||
We do not want to compile gcc each time, so even if it is a compile time dependency, we want to cache it.
|
||||
|
||||
This time, the command is a bit more involved:
|
||||
|
||||
```bash
|
||||
nix copy --to \
|
||||
's3://nix?endpoint=garage.deuxfleurs.fr®ion=garage&secret-key=/etc/nix/signing-key.sec' \
|
||||
$(nix-store -qR --include-outputs \
|
||||
$(nix-instantiate))
|
||||
```
|
||||
|
||||
This is the command we use in our CI as we expect the final binary to change, so we mainly focus on
|
||||
caching our development dependencies.
|
||||
|
||||
*Currently there is no automatic garbage collection of the cache: we should monitor its growth.
|
||||
Hopefully, we can erase it totally without breaking any build, the next build will only be slower.*
|
||||
|
||||
In practise, we concluded that we do not want to cache all the compilation dependencies.
|
||||
Instead, we want to cache the toolchain we use to build Garage each time we change it.
|
||||
So we removed from Drone any automatic update of the cache and instead handle them manually with:
|
||||
|
||||
```
|
||||
source ~/.awsrc
|
||||
nix-shell --attr cache --run 'refresh_cache'
|
||||
nix-shell --run 'refresh_toolchain'
|
||||
```
|
||||
|
||||
We don't automate this step at each CI build, as *there is currently no automatic garbage collection of the cache.*
|
||||
This means we should also monitor the cache's size; if it ever becomes too big we can erase it with:

||||

## Metadata snapshotting

It is good practice to setup automatic snapshotting of your metadata database

file, to recover from situations where it becomes corrupted on disk. This can

be done at the filesystem level if you are using ZFS or BTRFS.
|
||||
|
||||
Since Garage v0.9.4, Garage is able to take snapshots of the metadata database
|
||||
itself. This basically amounts to copying the database file, except that it can
|
||||
be run live while Garage is running without the risk of corruption or
|
||||
inconsistencies. This can be setup to run automatically on a schedule using
|
||||
[`metadata_auto_snapshot_interval`](@/documentation/reference-manual/configuration.md#metadata_auto_snapshot_interval).
|
||||
A snapshot can also be triggered manually using the `garage meta snapshot`
|
||||
command. Note that taking a snapshot using this method is very intensive as it
|
||||
requires making a full copy of the database file, so you might prefer using

filesystem-level snapshots if possible. To recover a corrupted node from such a

## Replacement scenario 3: corrupted metadata {#corrupted_meta}
|
||||
|
||||
In some cases, your metadata DB file might become corrupted, for instance if
|
||||
your node suffered a power outage and did not shut down properly. In this case,
|
||||
you can recover without having to change the node ID and rebuilding a cluster
|
||||
layout. This means that data blocks will not need to be shuffled around, you
|
||||
must simply find a way to repair the metadata file. The best way is generally
|
||||
to discard the corrupted file and recover it from another source.
|
||||
|
||||
First of all, start by locating the database file in your metadata directory,
|
||||
which [depends on your `db_engine`
|
||||
choice](@/documentation/reference-manual/configuration.md#db_engine). Then,
|
||||
your recovery options are as follows:
|
||||
|
||||
- **Option 1: resyncing from other nodes.** In case your cluster is replicated
|
||||
with two or three copies, you can simply delete the database file, and Garage
|
||||
will resync from other nodes. To do so, stop Garage, delete the database file
|
||||
or directory, and restart Garage. Then, do a full table repair by calling
|
||||
`garage repair -a --yes tables`. This will take a bit of time to complete as
|
||||
the new node will need to receive copies of the metadata tables from the
|
||||
network.
|
||||
|
||||
- **Option 2: restoring a snapshot taken by Garage.** Since v0.9.4, Garage can
|
||||
[automatically take regular
|
||||
snapshots](@/documentation/reference-manual/configuration.md#metadata_auto_snapshot_interval)
|
||||
of your metadata DB file. This file or directory should be located under
|
||||
`<metadata_dir>/snapshots`, and is named according to the UTC time at which it
|
||||
was taken. Stop Garage, discard the database file/directory and replace it by the
|
||||
snapshot you want to use. For instance, in the case of LMDB:
|
||||
|
||||
```bash
|
||||
cd $METADATA_DIR
|
||||
mv db.lmdb db.lmdb.bak
|
||||
cp -r snapshots/2024-03-15T12:13:52Z db.lmdb
|
||||
```
|
||||
|
||||
And for Sqlite:
|
||||
|
||||
```bash
|
||||
cd $METADATA_DIR
|
||||
mv db.sqlite db.sqlite.bak
|
||||
cp snapshots/2024-03-15T12:13:52Z db.sqlite
|
||||
```
|
||||
|
||||
Then, restart Garage and run a full table repair by calling `garage repair -a
|
||||
--yes tables`. This should run relatively fast as only the changes that
|
||||
occurred since the snapshot was taken will need to be resynchronized. Of
|
||||
course, if your cluster is not replicated, you will lose all changes that
|
||||
occurred since the snapshot was taken.
|
||||
|
||||

||||

Use the following command to launch the Garage server with our configuration file:
|
||||
|
||||
```
|
||||
garage -c path/to/garage.toml server
|
||||
garage server
|
||||
```
|
||||
|
||||
If you have placed the `garage.toml` file in `/etc` (its default location), you can simply run `garage server`.
|
||||
You can tune Garage's verbosity as follows (from less verbose to more verbose):
|
||||
|
||||
Alternatively, if you cannot or do not wish to run the Garage binary directly,
|
||||
you may use Docker to run Garage in a container using the following command:
|
||||
|
||||
```bash
|
||||
docker run \
|
||||
-d \
|
||||
--name garaged \

|
||||
Ensure your configuration file, `metadata_dir` and `data_dir` are readable by the user running the `garage` server or Docker.

|
||||
You can tune Garage's verbosity by setting the `RUST_LOG=` environment variable. \

### Top-level configuration options
|
||||
|
||||
#### `replication_factor` {#replication_factor}
|
||||
|
||||
The replication factor can be any positive integer smaller or equal the node count in your cluster.
|
||||
The chosen replication factor has a big impact on the cluster's failure tolerancy and performance characteristics.
|
||||
|
||||
- `1`: data stored on Garage is stored on a single node. There is no
|
||||
redundancy, and data will be unavailable as soon as one node fails or its
|
||||
network is disconnected. Do not use this for anything else than test
|
||||
deployments.
|
||||
|
||||
- `2`: data stored on Garage will be stored on two different nodes, if possible
|
||||
in different zones. Garage tolerates one node failure, or several nodes
|
||||
failing but all in a single zone (in a deployment with at least two zones),
|
||||
before losing data. Data remains available in read-only mode when one node is
|
||||
down, but write operations will fail.
|
||||
|
||||
- `3`: data stored on Garage will be stored on three different nodes, if
|
||||
possible each in a different zones. Garage tolerates two node failure, or
|
||||
several node failures but in no more than two zones (in a deployment with at
|
||||
least three zones), before losing data. As long as only a single node fails,
|
||||
or node failures are only in a single zone, reading and writing data to
|
||||
Garage can continue normally.
|
||||
|
||||
- `5`, `7`, ...: When setting the replication factor above 3, it is most useful to
|
||||
choose an uneven value, since for every two copies added, one more node can fail
|
||||
before losing the ability to write and read to the cluster.
|
||||
|
||||
Note that in modes `2` and `3`,
|
||||
if at least the same number of zones are available, an arbitrary number of failures in
|
||||
any given zone is tolerated as copies of data will be spread over several zones.
|
||||
|
||||
**Make sure `replication_factor` is the same in the configuration files of all nodes.
|
||||
Never run a Garage cluster where that is not the case.**
|
||||
|
||||
It is technically possible to change the replication factor although it's a
|
||||
dangerous operation that is not officially supported. This requires you to
|
||||
delete the existing cluster layout and create a new layout from scratch,
|
||||
meaning that a full rebalancing of your cluster's data will be needed. To do
|
||||
it, shut down your cluster entirely, delete the `custer_layout` files in the
|
||||
meta directories of all your nodes, update all your configuration files with
|
||||
the new `replication_factor` parameter, restart your cluster, and then create a
|
||||
new layout with all the nodes you want to keep. Rebalancing data will take
|
||||
some time, and data might temporarily appear unavailable to your users.
|
||||
It is recommended to shut down public access to the cluster while rebalancing
|
||||
is in progress. In theory, no data should be lost as rebalancing is a
|
||||
routine operation for Garage, although we cannot guarantee you that everything
|
||||
will go right in such an extreme scenario.
|
||||
|
||||
#### `consistency_mode` {#consistency_mode}
|
||||
|
||||
The consistency mode setting determines the read and write behaviour of your cluster.
|
||||
|
||||
- `consistent`: The default setting. This is what the paragraph above describes.
|
||||
The read and write quorum will be determined so that read-after-write consistency
|
||||
is guaranteed.
|
||||
- `degraded`: Lowers the read
|
||||
quorum to `1`, to allow you to read data from your cluster when several
|
||||
nodes (or nodes in several zones) are unavailable. In this mode, Garage
|
||||
does not provide read-after-write consistency anymore.
|
||||
The write quorum stays the same as in the `consistent` mode, ensuring that
|
||||
data successfully written to Garage is stored on multiple nodes (depending
|
||||
the replication factor).
|
||||
- `dangerous`: This mode lowers both the read
|
||||
and write quorums to `1`, to allow you to both read and write to your
|
||||
cluster when several nodes (or nodes in several zones) are unavailable. It
|
||||
is the least consistent mode of operation proposed by Garage, and also one
|
||||
that should probably never be used.
|
||||
|
||||
Changing the `consistency_mode` between modes while leaving the `replication_factor` untouched
|
||||
(e.g. setting your node's `consistency_mode` to `degraded` when it was previously unset, or from
|
||||
`dangerous` to `consistent`), can be done easily by just changing the `consistency_mode`
|
||||
parameter in your config files and restarting all your Garage nodes.
|
||||
|
||||
The consistency mode can be used together with various replication factors, to achieve
|
||||
a wide range of read and write characteristics. Some examples:
|
||||
|
||||
- Replication factor `2`, consistency mode `degraded`: While this mode
|
||||
technically exists, its properties are the same as with consistency mode `consistent`,
|
||||
since the read quorum with replication factor `2`, consistency mode `consistent` is already 1.
|
||||
|
||||
- Replication factor `2`, consistency mode `dangerous`: written objects are written to
|
||||
the second replica asynchronously. This means that Garage will return `200
|
||||
OK` to a PutObject request before the second copy is fully written (or even
|
||||
before it even starts being written). This means that data can more easily
|
||||
be lost if the node crashes before a second copy can be completed. This
|
||||
also means that written objects might not be visible immediately in read
|
||||
operations. In other words, this configuration severely breaks the consistency and
|
||||
durability guarantees of standard Garage cluster operation. Benefits of
|
||||
this configuration: you can still write to your cluster when one node is
|
||||
unavailable.
|
||||
|
||||
The quorums associated with each replication mode are described below:
|
||||
|
||||

Performance characteristics of the different DB engines are as follows:
|
||||
|
||||
- LMDB: the recommended database engine for high-performance distributed clusters.
|
||||
LMDB works very well, but is known to have the following limitations:
|
||||
- Sled: the default database engine, which tends to produce
|
||||
large data files and also has performance issues, especially when the metadata folder
|
||||
is on a traditional HDD and not on SSD.
|
||||
- LMDB: the recommended alternative on 64-bit systems,
|
||||
much more space-efficiant and slightly faster. Note that the data format of LMDB is not portable
|
||||
between architectures, so for instance the Garage database of an x86-64
|
||||
node cannot be moved to an ARM64 node. Also note that, while LMDB can technically be used on 32-bit systems,
|
||||
this will limit your node to very small database sizes due to how LMDB works; it is therefore not recommended.
|
||||
- Sqlite: Garage supports Sqlite as a storage backend for metadata,
|
||||
however it may have issues and is also very slow in its current implementation,
|
||||
so it is not recommended to be used for now.
|
||||
|
||||
- The data format of LMDB is not portable between architectures, so for
|
||||
instance the Garage database of an x86-64 node cannot be moved to an ARM64
|
||||
node.
|
||||
|
||||
- While LMDB can technically be used on 32-bit systems, this will limit your
|
||||
node to very small database sizes due to how LMDB works; it is therefore
|
||||
not recommended.
|
||||
|
||||
- Several users have reported corrupted LMDB database files after an unclean
|
||||
shutdown (e.g. a power outage). This situation can generally be recovered
|
||||
from if your cluster is geo-replicated (by rebuilding your metadata db from
|
||||
other nodes), or if you have saved regular snapshots at the filesystem
|
||||
level.
|
||||
|
||||
- Keys in LMDB are limited to 511 bytes. This limit translates to limits on
|
||||
object keys in S3 and sort keys in K2V that are limted to 479 bytes.
|
||||
|
||||
- Sqlite: Garage supports Sqlite as an alternative storage backend for
|
||||
metadata, which does not have the issues listed above for LMDB.
|
||||
On versions 0.8.x and earlier, Sqlite should be avoided due to abysmal
|
||||
performance, which was fixed with the addition of `metadata_fsync`.
|
||||
Sqlite is still probably slower than LMDB due to the way we use it,
|
||||
so it is not the best choice for high-performance storage clusters,
|
||||
but it should work fine in many cases.

||||

It is possible to convert Garage's metadata directory from one format to another
|
||||
using the `garage convert-db` command, which should be used as follows:

If this value is set, Garage will automatically take a snapshot of the metadata

DB file at a regular interval and save it in the metadata directory.
|
||||
This parameter can take any duration string that can be parsed by
|
||||
the [`parse_duration`](https://docs.rs/parse_duration/latest/parse_duration/#syntax) crate.
|
||||
|
||||
Snapshots can allow to recover from situations where the metadata DB file is

corrupted, for instance after an unclean shutdown. See [this

|
||||
Garage keeps only the two most recent snapshots of the metadata DB and deletes
|
||||
older ones automatically.
|
||||
|
||||
Note that taking a metadata snapshot is a relatively intensive operation as the
|
||||
entire data file is copied. A snapshot being taken might have performance
|
||||
impacts on the Garage node while it is running. If the cluster is under heavy
|
||||
write load when a snapshot operation is running, this might also cause the
|
||||
database file to grow in size significantly as pages cannot be recycled easily.

||||
For this reason, it might be better to use filesystem-level snapshots instead

||||
if possible.

#### `disable_scrub` {#disable_scrub}

|
||||
By default, Garage runs a scrub of the data directory approximately once per
|
||||
month, with a random delay to avoid all nodes running at the same time. When
|
||||
it scrubs the data directory, Garage will read all of the data files stored on
|
||||
disk to check their integrity, and will rebuild any data files that it finds
|
||||
corrupted, using the remaining valid copies stored on other nodes.
|
||||
See [this page](@/documentation/operations/durability-repairs.md#scrub) for details.
|

||||
Set the `disable_scrub` configuration value to `true` if you don't need Garage

### `sled_cache_capacity`
|
||||
|
||||
A limit on the total size of data blocks kept in RAM by S3 API nodes awaiting
|
||||
to be sent to storage nodes asynchronously.
|
||||
This parameter can be used to tune the capacity of the cache used by
|
||||
[sled](https://sled.rs), the database Garage uses internally to store metadata.
|
||||
Tune this to fit the RAM you wish to make available to your Garage instance.
|
||||
This value has a conservative default (128MB) so that Garage doesn't use too much
|
||||
RAM by default, but feel free to increase this for higher performance.
|
||||
|
||||
Explanation: since Garage wants to tolerate node failures, it uses quorum
|
||||
writes to send data blocks to storage nodes: try to write the block to three
|
||||
nodes, and return ok as soon as two writes complete. So even if all three nodes
|
||||
are online, the third write always completes asynchronously. In general, there
|
||||
are not many writes to a cluster, and the third asynchronous write can
|
||||
terminate early enough so as to not cause unbounded RAM growth. However, if
|
||||
the S3 API node is continuously receiving large quantities of data and the
|
||||
third node is never able to catch up, many data blocks will be kept buffered in
|
||||
RAM as they are awaiting transfer to the third node.
|
||||
### `sled_flush_every_ms`
|
||||
|
||||
The `block_ram_buffer_max` sets a limit to the size of buffers that can be kept
|
||||
in RAM in this process. When the limit is reached, backpressure is applied
|
||||
back to the S3 client.
|
||||
This parameters can be used to tune the flushing interval of sled.
|
||||
Increase this if sled is thrashing your SSD, at the risk of losing more data in case
|
||||
of a power outage (though this should not matter much as data is replicated on other
|
||||
nodes). The default value, 2000ms, should be appropriate for most use cases.
|
||||
|
||||
Note that this only counts buffers that have arrived to a certain stage of
|
||||
processing (received from the client + encrypted and/or compressed as
|
||||
necessary) and are ready to send to the storage nodes. Many other buffers will
|
||||
not be counted and this is not a hard limit on RAM consumption. In particular,
|
||||
if many clients send requests simultaneously with large objects, the RAM
|
||||
consumption will always grow linearly with the number of concurrent requests,
|
||||
as each request will use a few buffers of size `block_size` for receiving and
|
||||
intermediate processing before even trying to send the data to the storage
|
||||
node.

The default value is 256MiB.

|

#### `compression_level` {#compression_level}
|
||||
### `replication_mode`
|
||||
|
||||
Garage supports the following replication modes:
|
||||
|
||||
- `none` or `1`: data stored on Garage is stored on a single node. There is no
|
||||
redundancy, and data will be unavailable as soon as one node fails or its
|
||||
network is disconnected. Do not use this for anything else than test
|
||||
deployments.
|
||||
|
||||
- `2`: data stored on Garage will be stored on two different nodes, if possible
|
||||
in different zones. Garage tolerates one node failure, or several nodes
|
||||
failing but all in a single zone (in a deployment with at least two zones),
|
||||
before losing data. Data remains available in read-only mode when one node is
|
||||
down, but write operations will fail.
|
||||
|
||||
- `2-dangerous`: a variant of mode `2`, where written objects are written to
|
||||
the second replica asynchronously. This means that Garage will return `200
|
||||
OK` to a PutObject request before the second copy is fully written (or even
|
||||
before it even starts being written). This means that data can more easily
|
||||
be lost if the node crashes before a second copy can be completed. This
|
||||
also means that written objects might not be visible immediately in read
|
||||
operations. In other words, this mode severely breaks the consistency and
|
||||
durability guarantees of standard Garage cluster operation. Benefits of
|
||||
this mode: you can still write to your cluster when one node is
|
||||
unavailable.
|
||||
|
||||
- `3`: data stored on Garage will be stored on three different nodes, if
|
||||
possible each in a different zones. Garage tolerates two node failure, or
|
||||
several node failures but in no more than two zones (in a deployment with at
|
||||
least three zones), before losing data. As long as only a single node fails,
|
||||
or node failures are only in a single zone, reading and writing data to
|
||||
Garage can continue normally.
|
||||
|
||||
- `3-degraded`: a variant of replication mode `3`, that lowers the read
|
||||
quorum to `1`, to allow you to read data from your cluster when several
|
||||
nodes (or nodes in several zones) are unavailable. In this mode, Garage
|
||||
does not provide read-after-write consistency anymore. The write quorum is
|
||||
still 2, ensuring that data successfully written to Garage is stored on at
|
||||
least two nodes.
|
||||
|
||||
- `3-dangerous`: a variant of replication mode `3` that lowers both the read
|
||||
and write quorums to `1`, to allow you to both read and write to your
|
||||
cluster when several nodes (or nodes in several zones) are unavailable. It
|
||||
is the least consistent mode of operation proposed by Garage, and also one
|
||||
that should probably never be used.
|
||||
|
||||
Note that in modes `2` and `3`,
|
||||
if at least the same number of zones are available, an arbitrary number of failures in
|
||||
any given zone is tolerated as copies of data will be spread over several zones.
|
||||
|
||||
**Make sure `replication_mode` is the same in the configuration files of all nodes.
|
||||
Never run a Garage cluster where that is not the case.**
|
||||
|
||||
The quorums associated with each replication mode are described below:
|
||||
|
||||
| `replication_mode` | Number of replicas | Write quorum | Read quorum | Read-after-write consistency? |
|
||||
| ------------------ | ------------------ | ------------ | ----------- | ----------------------------- |
|
||||
| `none` or `1` | 1 | 1 | 1 | yes |
|
||||
| `2` | 2 | 2 | 1 | yes |
|
||||
| `2-dangerous` | 2 | 1 | 1 | NO |
|
||||
| `3` | 3 | 2 | 2 | yes |
|
||||
| `3-degraded` | 3 | 2 | 1 | NO |
|
||||
| `3-dangerous` | 3 | 1 | 1 | NO |
|
||||
|
||||
Changing the `replication_mode` between modes with the same number of replicas
|
||||
(e.g. from `3` to `3-degraded`, or from `2-dangerous` to `2`), can be done easily by
|
||||
just changing the `replication_mode` parameter in your config files and restarting all your
|
||||
Garage nodes.
|
||||
|
||||
It is also technically possible to change the replication mode to a mode with a
|
||||
different numbers of replicas, although it's a dangerous operation that is not
|
||||
officially supported. This requires you to delete the existing cluster layout
|
||||
and create a new layout from scratch, meaning that a full rebalancing of your
|
||||
cluster's data will be needed. To do it, shut down your cluster entirely,
|
||||
delete the `custer_layout` files in the meta directories of all your nodes,
|
||||
update all your configuration files with the new `replication_mode` parameter,
|
||||
restart your cluster, and then create a new layout with all the nodes you want
|
||||
to keep. Rebalancing data will take some time, and data might temporarily
|
||||
appear unavailable to your users. It is recommended to shut down public access
|
||||
to the cluster while rebalancing is in progress. In theory, no data should be
|
||||
lost as rebalancing is a routine operation for Garage, although we cannot
|
||||
guarantee you that everything will go right in such an extreme scenario.

### The `[consul_discovery]` section
|
||||
## The `[consul_discovery]` section
|
||||
|
||||
Garage supports discovering other nodes of the cluster using Consul. For this
|
||||
to work correctly, nodes need to know their IP address by which they can be
|
||||
reached by other nodes of the cluster, which should be set in `rpc_public_addr`.
|
||||
|
||||
#### `consul_http_addr` {#consul_http_addr}
|
||||
### `consul_http_addr` and `service_name`
|
||||

The `consul_http_addr` parameter should be set to the full HTTP(S) address of the Consul server.
|
||||
|
||||
#### `api` {#consul_api}
|
||||
### `api`
|
||||
|
||||
Two APIs for service registration are supported: `catalog` and `agent`. `catalog`, the default, will register a service using
|
||||
the `/v1/catalog` endpoints, enabling mTLS if `client_cert` and `client_key` are provided. The `agent` API uses the
|
||||
`v1/agent` endpoints instead, where an optional `token` may be provided.
|
||||
|
||||
#### `service_name` {#consul_service_name}
|
||||
### `service_name`
|
||||
|
||||
`service_name` should be set to the service name under which Garage's
|
||||

### The `[kubernetes_discovery]` section
|
||||
## The `[kubernetes_discovery]` section
|
||||
|
||||
Garage supports discovering other nodes of the cluster using kubernetes custom
|
||||
resources. For this to work, a `[kubernetes_discovery]` section must be present
|
||||
with at least the `namespace` and `service_name` parameters.
|
||||
|
||||
#### `namespace` {#kube_namespace}
|
||||
### `namespace`
|
||||
|
||||
`namespace` sets the namespace in which the custom resources are
|
||||
configured.
|
||||
|
||||
#### `service_name` {#kube_service_name}
|
||||
### `service_name`
|
||||
|
||||
`service_name` is added as a label to the advertised resources to
|
||||
filter them, to allow for multiple deployments in a single namespace.

||||
|
||||
#### `skip_crd` {#kube_skip_crd}

title = "Migrating from 0.8 to 0.9"
|

weight = 12
|

+++
|
||||
|
||||
**This guide explains how to migrate to 0.9 if you have an existing 0.8 cluster.
|
||||
We don't recommend trying to migrate to 0.9 directly from 0.7 or older.**
|
||||
|
||||
This migration procedure has been tested on several clusters without issues.
|
||||
However, it is still a *critical procedure* that might cause issues.
|
||||
**Make sure to back up all your data before attempting it!**
|
||||
|
||||
You might also want to read our [general documentation on upgrading Garage](@/documentation/operations/upgrading.md).
|
||||
|
||||
The following are **breaking changes** in Garage v0.9 that require your attention when migrating:
|
||||
|
||||
- LMDB is now the default metadata db engine and Sled is deprecated. If you were using Sled, make sure to specify `db_engine = "sled"` in your configuration file, or take the time to [convert your database](https://garagehq.deuxfleurs.fr/documentation/reference-manual/configuration/#db-engine-since-v0-8-0).
|
||||
|
||||
- Capacity values are now in actual byte units. The translation from the old layout will assign 1 capacity = 1Gb by default, which might be wrong for your cluster. This does not cause any data to be moved around, but you might want to re-assign correct capacity values post-migration.
|
||||
|
||||
- Multipart uploads that were started in Garage v0.8 will not be visible in Garage v0.9 and will have to be restarted from scratch.
|
||||
|
||||
- Changes to the admin API: some `v0/` endpoints have been replaced by `v1/` counterparts with updated/uniformized syntax. All other endpoints have also moved to `v1/` by default, without syntax changes, but are still available under `v0/` for compatibility.
|
||||
|
||||
|
||||
## Simple migration procedure (takes cluster offline for a while)
|
||||
|
||||
The migration steps are as follows:
|
||||
|
||||
1. Disable API and web access. You may do this by stopping your reverse proxy or by commenting out
|
||||
the `api_bind_addr` values in your `config.toml` file and restarting Garage.
|
||||
2. Do `garage repair --all-nodes --yes tables` and `garage repair --all-nodes --yes blocks`,
|
||||
check the logs and check that all data seems to be synced correctly between
|
||||
nodes. If you have time, do additional checks (`versions`, `block_refs`, etc.)
|
||||
3. Check that the block resync queue and Merkle queue are empty:
|
||||
run `garage stats -a` to query them or inspect metrics in the Grafana dashboard.
|
||||
4. Turn off Garage v0.8
|
||||
5. **Backup the metadata folder of all your nodes!** For instance, use the following command
|
||||
if your metadata directory is `/var/lib/garage/meta`: `cd /var/lib/garage ; tar -acf meta-v0.8.tar.zst meta/`
|
||||
6. Install Garage v0.9
|
||||
7. Update your configuration file if necessary.
|
||||
8. Turn on Garage v0.9
|
||||
9. Do `garage repair --all-nodes --yes tables` and `garage repair --all-nodes --yes blocks`.
|
||||
Wait for a full table sync to run.

10. Your upgraded cluster should be in a working state. Re-enable API and Web
|
||||
access and check that everything went well.
|
||||
11. Monitor your cluster in the next hours to see if it works well under your production load, report any issue.
|
||||
12. You might want to assign correct capacity values to all your nodes. Doing so might cause data to be moved
|
||||
in your cluster, which should also be monitored carefully.

## Minimal downtime migration procedure
|
||||
|
||||
The migration to Garage v0.9 can be done with almost no downtime,
|
||||
by restarting all nodes at once in the new version.
|
||||
|
||||
The migration steps are as follows:
|
||||
|
||||
1. Do `garage repair --all-nodes --yes tables` and `garage repair --all-nodes --yes blocks`,
|
||||
check the logs and check that all data seems to be synced correctly between
|
||||
nodes. If you have time, do additional checks (`versions`, `block_refs`, etc.)
|
||||
|
||||
2. Turn off each node individually; back up its metadata folder (see above); turn it back on again.
|
||||
This will allow you to take a backup of all nodes without impacting global cluster availability.
|
||||
You can do all nodes of a single zone at once as this does not impact the availability of Garage.
|
||||
|
||||
3. Prepare your binaries and configuration files for Garage v0.9
|
||||
|
||||
4. Shut down all v0.8 nodes simultaneously, and restart them all simultaneously in v0.9.
|
||||
Use your favorite deployment tool (Ansible, Kubernetes, Nomad) to achieve this as fast as possible.
|
||||
Garage v0.9 should be in a working state as soon as it starts.
|
||||
|
||||
5. Proceed with repair and monitoring as described in steps 9-12 above.

**This guide explains how to migrate to 1.0 if you have an existing 0.9 cluster.
|
||||
We don't recommend trying to migrate to 1.0 directly from 0.8 or older.**
|
||||
|
||||
This migration procedure has been tested on several clusters without issues.
|
||||
However, it is still a *critical procedure* that might cause issues.
|
||||
**Make sure to back up all your data before attempting it!**
|
||||
|
||||
You might also want to read our [general documentation on upgrading Garage](@/documentation/operations/upgrading.md).
|
||||
|
||||
## Changes introduced in v1.0
|
||||
|
||||
The following are **breaking changes** in Garage v1.0 that require your attention when migrating:
|
||||
|
||||
- The Sled metadata db engine has been **removed**. If your cluster was still
|
||||
using Sled, you will need to **use a Garage v0.9.x binary** to convert the
|
||||
database using the `garage convert-db` subcommand. See
|
||||
[here](@/documentation/reference-manual/configuration.md#db_engine) for the
|
||||
details of the procedure.
|
||||
|
||||
The following syntax changes have been made to the configuration file:
|
||||
|
||||
- The `replication_mode` parameter has been split into two parameters:
|
||||
[`replication_factor`](@/documentation/reference-manual/configuration.md#replication_factor)
|
||||
and
|
||||
[`consistency_mode`](@/documentation/reference-manual/configuration.md#consistency_mode).
|
||||
The old syntax using `replication_mode` is still supported for legacy
|
||||
reasons and can still be used.
|
||||
|
||||
- The parameters `sled_cache_capacity` and `sled_flush_every_ms` have been removed.
|
||||
|
||||
## Migration procedure
|
||||
|
||||
The migration to Garage v1.0 can be done with almost no downtime,
|
||||
by restarting all nodes at once in the new version.
|
||||
|
||||
The migration steps are as follows:
|
||||
|
||||
1. Do a `garage repair --all-nodes --yes tables`, check the logs and check that
|
||||
all data seems to be synced correctly between nodes. If you have time, do
|
||||
additional `garage repair` procedures (`blocks`, `versions`, `block_refs`,
|
||||
etc.)
|
||||
|
||||
2. Ensure you have a snapshot of your Garage installation that you can restore
|
||||
to in case the upgrade goes wrong:
|
||||
|
||||
- If you are running Garage v0.9.4 or later, use the `garage meta snapshot
|
||||
--all` to make a backup snapshot of the metadata directories of your nodes
|
||||
for backup purposes, and save a copy of the following files in the
|
||||
metadata directories of your nodes: `cluster_layout`, `data_layout`,
|
||||
`node_key`, `node_key.pub`.
|
||||
|
||||
- If you are running a filesystem such as ZFS or BTRFS that support
|
||||
snapshotting, you can create a filesystem-level snapshot to be used as a
|
||||
restoration point if needed.
|
||||
|
||||
- In other cases, make a backup using the old procedure: turn off each node
|
||||
individually; back up its metadata folder (for instance, use the following
|
||||
command if your metadata directory is `/var/lib/garage/meta`: `cd
|
||||
/var/lib/garage ; tar -acf meta-v0.9.tar.zst meta/`); turn it back on
|
||||
again. This will allow you to take a backup of all nodes without
|
||||
impacting global cluster availability. You can do all nodes of a single
|
||||
zone at once as this does not impact the availability of Garage.
|
||||
|
||||
3. Prepare your updated binaries and configuration files for Garage v1.0
|
||||
|
||||
4. Shut down all v0.9 nodes simultaneously, and restart them all simultaneously
|
||||
in v1.0. Use your favorite deployment tool (Ansible, Kubernetes, Nomad) to
|
||||
achieve this as fast as possible. Garage v1.0 should be in a working state
|
||||
as soon as enough nodes have started.
|
||||
|
||||
5. Monitor your cluster in the following hours to see if it works well under
|
||||
your production load.

How indexing works:

|
||||
- Each node keeps a local count of how many items it stores for each partition,

in a local database tree that is updated atomically when an item is modified.

in a local Sled tree that is updated atomically when an item is modified.

\underline{Constraints:} slow network (geographical distance), node unavailability/crashes\\

\underline{Objective:} maximize availability, maintain an \emph{appropriate level of consistency}\\
|

\vspace{1em}

\begin{enumerate}

\vspace{1em}

\underline{Example:} \texttt{PutObject}\\
|

\vspace{.5em}
|
||||
If two clients write the same
|

object at the same time, one of the two is implicitly overwritten.
|

No need to coordinate, use a \emph{last-writer-wins register}.

\vspace{1em}

\vspace{1em}

\underline{Example:} \texttt{CreateBucket}\\
|

\vspace{.5em}
|

A bucket is a reserved name in a shared namespace,

two clients should be prevented from both creating the same bucket
|

(\emph{mutual exclusion}).

\vspace{1em}

Leaderless consensus (Antoniadis et al., 2023) alleviates issues with RAFT and PAXOS:
|
||||
\vspace{1em}
|
||||
\begin{itemize}
|
||||
\item \textbf{No leader.} All nodes participate equally at each time step,
|
||||
and different nodes can be unavailable at different times without issues.
|
||||
\\ \vspace{.5em} $\to$ better tolerance to the high latency (remove bottleneck issue)
|
||||
\\ $\to$ tolerates crash transparently
|
||||
\vspace{1em}
|

\item \textbf{Simpler formalization.} The algorithm is very simple to express and to analyze in mathematical terms.

\begin{itemize}

\item Global:
|

\begin{itemize}
|

\item Max. $\sim$100 nodes per cluster (excluding gateways)
|
||||
\end{itemize}
|
||||
\vspace{1em}
|
||||
\item Metadata:
|
||||
\begin{itemize}
|
||||
\item One big bucket = bottleneck, object list on 3 nodes only
|
||||
\end{itemize}
|
||||
\vspace{1em}
|
||||
\item Block manager:
|
||||
\begin{itemize}
|
||||
\item Lots of small files on disk
|
||||
\item Processing the resync queue can be slow
|
||||
\end{itemize}

\frametitle{Deployment advice for very large clusters}
|
||||
\begin{itemize}
|
||||
\item Metadata storage:
|
||||
\begin{itemize}
|
||||
\item ZFS mirror (x2) on fast NVMe
|
||||
\item Use LMDB storage engine
|
||||
\end{itemize}
|
||||
\vspace{.5em}
|
||||
\item Data block storage:
|
||||
\begin{itemize}
|
||||
\item Use Garage's native multi-HDD support
|
||||
\item XFS on individual drives
|
||||
\item Increase block size (1MB $\to$ 10MB, requires more RAM and good networking)
|
||||
\item Tune \texttt{resync-tranquility} and \texttt{resync-worker-count} dynamically
|
||||
\end{itemize}
|
||||
\vspace{.5em}
|
||||
\item Other :
|
||||
\begin{itemize}
|
||||
\item Split data over several buckets
|
||||
\item Use less than 100 storage nodes
|
||||
\item Use gateway nodes
|
||||
\end{itemize}
|
||||
\vspace{.5em}
|
||||
\end{itemize}
|
||||
Our deployments: $< 10$ TB. Some people have done more!

\begin{itemize}
|

\item Global:
|

\begin{itemize}
|
||||
\item Max. $\sim$100 nodes per cluster (excluding gateways)
|
||||
\end{itemize}
|
||||
\vspace{1em}
|
||||
\item Metadata:
|
||||
\begin{itemize}
|
||||
\item One big bucket = bottleneck, object list on 3 nodes only
|
||||
\end{itemize}
|
||||
\vspace{1em}
|
||||
\item Block manager:
|
||||
\begin{itemize}
|
||||
\item Lots of small files on disk
|
||||
\item Processing the resync queue can be slow
|

\frametitle{Deployment advice for very large clusters}
|
||||
\begin{itemize}
|
||||
\item Metadata storage:
|
||||
\begin{itemize}
|
||||
\item ZFS mirror (x2) on fast NVMe
|
||||
\item Use LMDB storage engine
|
||||
\end{itemize}
|
||||
\vspace{.5em}
|
||||
\item Data block storage:
|
||||
\begin{itemize}
|
||||
\item Use Garage's native multi-HDD support
|
||||
\item XFS on individual drives
|
||||
\item Increase block size (1MB $\to$ 10MB, requires more RAM and good networking)
|
||||
\item Tune \texttt{resync-tranquility} and \texttt{resync-worker-count} dynamically
|
||||
\end{itemize}
|
||||
\vspace{.5em}
|
||||
\item Other :
|
||||
\begin{itemize}
|
||||
\item Split data over several buckets
|
||||
\item Use less than 100 storage nodes
|
||||
\item Use gateway nodes
|
||||
\end{itemize}
|
||||
\vspace{.5em}
|
||||
\end{itemize}
|
||||
Our deployments: $< 10$ TB. Some people have done more!
