MISCONF Redis

[tomkolp]

Describe the issue

After this error, celery stops processing jobs. Maybe there is more useful information in sentry.

ResponseError
MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.

Additional context

docker compose stop and docker compose up temporarily solve the problem

Did you check the Redis logs as the error suggests? Maybe the disk is full?

This issue has been marked as a question by a Weblate team member. Why? Because it belongs more to the professional Weblate Care or community Discussions than here. We strive to answer these reasonably fast here, too, but purchasing the support subscription is more responsible and faster for your business. And it makes Weblate stronger as well. Thanks!

Where can I find the redis logs in Docker? I have about 5 GB of free space.

[nijel]

docker compose logs cache

[tomkolp]

I will check this log if the problem reoccurs. Currently, I only have logs available after restarting the container.

Edit:
The problem always occurs at night (this is the 3rd time, not every day). This may be related to the backup copy and there is indeed a lack of space.

[nijel]

Redis does dump it's content regularly and in that time it needs double disk space, check content of its volume to see how much it uses.

There was no mistake after the seat was cleared tonight. I think that was a real problem.
