runrun Posted October 14, 2021 Share Posted October 14, 2021 (edited) First things first: Unraid version: 6.9.2 Plugins, addons, and hardware listed in Diagnostic zip hal-diagnostics-20211013-2232.zip Problem: I do not see any of my shares in the shares tab of Unraid I can access files by navigating to their /mnt/disk#/... location via the console but /mnt/user is empty How I noticed the problem: I went to drop a file into a share (from Windows 10) and got an error saying the drive was write-protected I stopped my docker containers, ran "Docker Safe New Perms" on everything but appdata, but I was still unable to write to my shares I rebooted then started the array but no shares showed up What probably caused it: I changed the cache disk/pool for my appdata and system shares and I *think* all my Docker containers were running while I did so I honestly don't recall which disk/pool they were previously using as a cache (it was either "system_cache" or "cache_protected") but the new target cache was "cache_ssd" I'm not freaking out because I'm pretty confident all my data is still intact, but it would be nice if I could access it Any help would be greatly appreciated!

itimpi Posted October 14, 2021 Share Posted October 14, 2021 I think your changing no pools is probably not relevant. according to your syslog you are getting BTRFS errors reported on your Samsung SSD. I have no idea how serious these are but you should try and run a file system check/repair as described here in the online docum3ntstion accessible via the ‘Manual’ link at th3 bottom of the Unraid GUI. 2 hours ago, runrun said: I changed the cache disk/pool for my appdata and system shares and I *think* all my Docker containers were running while I did so Note that Unraid would not automatically move any files/folders between the pools when you make such a change so you would probably end up with bits of each share on both pools unless you took specific action to move them over.

runrun Posted October 15, 2021 Author Share Posted October 15, 2021 Thanks for the reply! I ran the filesystem check/repair, rebooted my system and I got my shares back! Alas, I'm still seeing a ton of errors in my log and sdh1 is conspicuously empty of files (though there are some directories). I imagine something is borked in the partition table, but I really don't know anything about BTRFS so I could be totally off base kernel: BTRFS error (device sdh1): bad tree block start, want 1023298699264 have 0 Quote Link to comment
ChatNoir Posted October 15, 2021 Share Posted October 15, 2021 You should post new diagnostics. Quote Link to comment
JorgeB Posted October 15, 2021 Share Posted October 15, 2021 With most btrfs filesystem corruption issues best bet is to backup and re-format the device/pool, than restore the data. Quote Link to comment
