Corrupted file (bad disk) in Unraid docker appdata

Server Version#: 1.43.0.10492
Player Version#: 4.156.0

I have a failing cache drive in my Unraid server. Trying to back it up prior to replacement I found out that my com.plexapp.plugins.library.db-wal is apparently in the bad area of the disk and won’t backup correctly. I have been experiencing random play failures when streaming music. Maybe related?

How important is that file? What will I lose if I simply delete it to get a successful backup? Any words of wisdom regarding this situation?

This is a kind of “journal”, where the database engine is keeping all the changes that were made to the database in the current session. (that explanation is not 100% accurate, but good enough for our purpose here)

It is usually no big deal to just delete

com.plexapp.plugins.library.db-wal 
com.plexapp.plugins.library.db-shm

together, while Plex server is shut down.
(But of course keep the main file com.plexapp.plugins.library.db)
You may lose some changes to the database from the last session, but it is rarely something substantial.

It might be good to use this https://github.com/ChuckPa/DBRepair afterwards, and avoid major issues before starting up the server again.

Oh, great! Deleted those two files, started another backup and now I have a ‘GoP-0.xml’ file failure. Any harm in deleting that?

Sorry, no idea where that might come from and what it is for.

Took the plunge and deleted that file as well. Plex on the docker is back up and running with no discernable issues or changes.

Thanks!
