Well I'm sorry to report I did not make it to day 3. Database corruption happened either last night or this morning. In any case, back to 6.6.7.

Well its been 2 days since I've upgraded to the 6.8.0 rc and I can safely report there has been no corruption. I've downloaded over 100GB using sonarr and I've been recording TV on Plex and no apps have presented any indication of corruption (nor do the logs show). I am keeping my fingers crossed and hoping this keeps up.

I can 100% confirm I never had any database corruption while my appdata was on a cache drive (and running the latest stable Unraid 6.7.x). During this time, I was running both Plex and Sonarr concurrently. I had upgraded my array 2 months ago to use just NVMe drives without a cache and after the upgrade I was only using Plex and not Sonarr. Granted I had Sonarr running, but it was not doing anything since I did not have my indexers setup. Everything was working perfectly with my appdata on /mnt/disk1. Now a few days ago, I decided to get Sonarr back up and running. Within an hour (while performing tasks in both Sonarr and Plex), I had database corruption on both my Plex and Sonarr databases. Everytime i restored a backup, it would inevitably become corrupted again. Since then, I had to disable Sonarr to prevent whatever is causing SQLite to misbehave. I have not tried any of the latest RC releases but I'll give it a shot this weekend.

I also have this set to auto.

I also started experiencing constant Plex database corruption after upgrading to the RC release of 6.7.0 (this was a few months ago). Unfortunately the only way to fix it was to switch the config to the cache disk. This kind of puts a dent in my plan to get rid of my cache disks since I was planning on running my array on solely NVME drives. I do hope this issue gets resolved soon.
