My guess is that each media is first written on the local filesystem and then sent on S3. My guess is that each media is first written on the local filesystem and then sent on S3.
Because GlusterFS is slow and error prone, some exceptions or timeouts may be risen before the file is uploaded to S3. Because GlusterFS is slow and error prone, some exceptions or timeouts may be risen before the file is uploaded to S3.

I presented the "native" way to handle media on Matrix Synapse but there is also a community managed project named [`matrix-media-repo`](https://docs.t2bot.io/matrix-media-repo) with a slightly different goal. The author wanted to have a common media repository for multiple servers to reduce storage costs.

matrix-media-repo works is not implementation independent: instead, it shadows the matrix endpoint used for the media `/_matrix/media` and thus is compatible with any matrix server, like dendrite or conduit. Its main advantage over our solution is that it does not have this mandatory cache, it can directly upload and serve from a S3 backend, simplifying the management. matrix-media-repo is not implementation independent: instead, it shadows the matrix endpoint used for the media `/_matrix/media` and thus is compatible with any matrix server, like dendrite or conduit.

Depending on your reverse proxy, it might be possible that if `matrix-media-repo` is down, users are redirected to the original endpoint that should not be used anymore, leading to loss of data and strange behaviors. It seems that [an option](https://github.com/matrix-org/synapse/blob/v1.42.0/synapse/config/server.py#L265-L269) in Synapse allows to deactivate the media-repo, it might save you some time if it works.
