June 2, 20197 yr I've been facing an issue where my com.plexapp.plugins.library.db DB corrupts. I've narrowed it down with this repro: Download a new TV show Place it in my TV media directory Plex will notice a new show was added and start to add it to my Plex library The DB will corrupt I then need to restore my db files from the previous days backup. I then click "Scan Library Files" in Plex to find the missing TV show, it finds and adds it without issue. Things work great until it automatically finds new media. This is how I restore: DATE="2019-06-01" rm -f com.plexapp.plugins.library.db-shm rm -f com.plexapp.plugins.library.db-wal rm -f com.plexapp.plugins.library.blobs.db rm -f com.plexapp.plugins.library.db cp com.plexapp.plugins.library.blobs.db-$DATE com.plexapp.plugins.library.blobs.db cp com.plexapp.plugins.library.db-$DATE com.plexapp.plugins.library.db Anyone have any idea of what could be going on? I've tried changing my config directory from /mnt/user/appdata/plex to /mnt/user/cache/plex and that causes 100% corruption 100% of the time. I can't even get Plex to start when I point at /mnt/user/cache/plex. I've ran SMART on the disk that contains the DB and there are no errors. I run a VM on the SSD cache drive and have no issues. My cache drive (SSD) has this SMART self-test history: Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Vendor (0x60) Completed without error 00% 4108 - # 2 Offline Completed without error 00% 0 - # 3 Offline Completed without error 00% 0 - # 4 Offline Completed without error 00% 0 - # 5 Vendor (0x54) Completed without error 00% 0 - # 6 Vendor (0xb3) Unknown status (0xe) 60% 211 - # 7 Vendor (0x9d) Unknown status (0xe) 50% 57544 - # 8 Vendor (0xa5) Unknown status (0xe) 50% 57032 - # 9 Offline Completed without error 00% 0 - #10 Offline Completed without error 00% 64 - #11 Offline Completed without error 00% 0 - #12 Offline Completed without error 00% 0 - #13 Offline Completed without error 00% 0 - And this SMART error log: Warning: ATA error count 2830 inconsistent with error log pointer 4 ATA Error Count: 2830 (device log contains only the most recent five errors) CR = Command Register [HEX] FR = Features Register [HEX] SC = Sector Count Register [HEX] SN = Sector Number Register [HEX] CL = Cylinder Low Register [HEX] CH = Cylinder High Register [HEX] DH = Device/Head Register [HEX] DC = Device Command Register [HEX] ER = Error register [HEX] ST = Status register [HEX] Powered_Up_Time is measured from power on, and printed as DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes, SS=sec, and sss=millisec.

June 2, 20197 yr It's /mnt/cache, not /mnt/user/cache. The last still goes through the fuse system and might cause sqlite database corruption. You do have a cache drive? If not, you need to move the plex appdata to on disk and use /mnt/diskX as that goes directly to disk the same way as using /mnt/cache.
June 2, 20197 yr Author Thank you very much. I’m out right now but will test this as soon as I return and update this thread with the results.
June 2, 20197 yr Author No luck when using /mnt/cache. I copied everything there and the corruption still occurs, even if I restore from a good copy.
June 3, 20197 yr Author I was able to get it up and running on /mnt/disk3. Problem was permissions on the db files. Added +w and I'm good there now. I'll see how things go for a few days and report back.
June 3, 20197 yr Author One additional note, /mnt/cache works as well, same permissions issue. add "chmod +w *" on the db files fixed my loading issue. I'll run it on the cache drive for a few days. I guess with this, I'll need to backup to the array manually?
