BDPM Posted June 26, 2019 Share Posted June 26, 2019 I did the following AFTER the 6.7.2 update, along with a radarr update I believe. I was watching a movie on my plex this morning. I also was checking sonarr and radarr this morning. Everything was working as far as I could tell. I went and ran some errands, stopped for lunch, then came home to plex locked up. It wouldnt restart. So I just rebooted the server. When it came back up all of my docker containers are gone and the appdata folder is empty... HELP!!! I do have appdata backup and it was successfully backed up last night, but I would like someone who is smarter than I to suggest method to get back up and running.

saarg Posted June 26, 2019 Share Posted June 26, 2019 Looks like your cache drive has some issues. You need to check the filesystem for errors and fix them. It should be mentioned how in a sticked FAQ.

BDPM Posted June 26, 2019 Author Share Posted June 26, 2019 Okay.. so I noticed that one of the cache drives in the cache pool was missing. I shutdown the server, jiggled the cables for the cache drives, made sure they had power and data cables were secure. They are the clippy kind so I dont know why they could have gotten loose, but when I rebooted, the cache pool started the rebuild of btrfs thing and all of the containers and appdata folder is restored. whew... that freaked me out for a few minutes there. Any input to prevent more freaking out in the future would be appreciated. I think I would rather have a bigger cache drive than pooling two 120's. BDPM Quote Link to comment
