I upgraded from unRaid 6.6.7 to 6.7.0 last Sunday, May 12th. Almost immediately, my plex database was corrupted. Since then I have tried the linuxserver, plexinc and limetech containers, all have crashed with a corrupted database. I totally delete the plex folder in appdata before I reinstall, and still it gets corrupted. I have reboot my unRaid numerous times, before installing a new container into an empty folder. Still I get corruptions. A few minutes ago I reverted to unRaid 6.6.7 from 6.7.0, and am testing to see if that makes any difference. I’ll update this post when I’m sure it makes a difference, or not.
Wish me luck
