**This guide explains how to migrate to 0.6 if you have an existing 0.5 cluster.
|
|
We don't recommend trying to migrate directly from 0.4 or older to 0.6.**
|
|
|
|
**We make no guarantee that this migration will work perfectly:
|
|
back up all your data before attempting it!**
|
|
|
|
Garage v0.6 (not yet released) introduces a new data model for buckets,
|
|
that allows buckets to have many names (aliases).
|
|
Buckets can also have "private" aliases (called local aliases),
|
|
which are only visible when using a certain access key.
|
|
|
|
This new data model means that the metadata tables have changed quite a bit in structure,
|
|
and a manual migration step is required.
|
|
|
|
The migration steps are as follows:
|
|
|
|
1. Disable api and web access for some time (Garage does not support disabling
|
|
these endpoints but you can change the port number or stop your reverse
|
|
proxy for instance).
|
|
|
|
2. Do `garage repair -a --yes tables` and `garage repair -a --yes blocks`,
|
|
check the logs and check that all data seems to be synced correctly between
|
|
nodes.
|
|
|
|
4. Turn off Garage 0.5
|
|
|
|
5. **Backup your metadata folders!!**
|
|
|
|
6. Turn on Garage 0.6
|
|
|
|
7. At this point, `garage bucket list` should indicate that no buckets are present
|
|
in the cluster. `garage key list` should show all of the previously existing
|
|
access key, however these keys should not have any permissions to access buckets.
|
|
|
|
8. Run `garage migrate buckets050`: this will populate the new bucket table with
|
|
the buckets that existed previously. This will also give access to API keys
|
|
as it was before.
|
|
|
|
9. Check that all your buckets indeed appear in `garage bucket list`, and that
|
|
keys have the proper access flags set. If that is not the case, revert
|
|
everything and file a bug!
|
|
|
|
10. Your upgraded cluster should be in a working state. Re-enable API and Web
|
|
access and check that everything went well.
