MystX Posted April 24, 2020 Share Posted April 24, 2020 (edited) Hi guys, I ran pm-suspend on my unraid server to try to fix the header type 127 VM bug. I woke the server up and it hadn't worked. So I rebooted it. Now I get the following errors on the console when the cache drive ties to mount: Apr 24 19:47:17 Krieger emhttpd: shcmd (73): mount -t btrfs -o noatime,nodiratime -U 654c77cd-a2b1-470a-bebe-55a1287689f0 /mnt/cache Apr 24 19:47:17 Krieger kernel: BTRFS info (device dm-2): disk space caching is enabled Apr 24 19:47:17 Krieger kernel: BTRFS info (device dm-2): has skinny extents Apr 24 19:47:17 Krieger kernel: BTRFS error (device dm-2): bad tree block start, want 483444981760 have 8354356187505211028 Apr 24 19:47:17 Krieger kernel: BTRFS error (device dm-2): failed to read block groups: -5 Apr 24 19:47:17 Krieger kernel: BTRFS error (device dm-2): open_ctree failed Apr 24 19:47:17 Krieger root: mount: /mnt/cache: wrong fs type, bad option, bad superblock on /dev/mapper/nvme0n1p1, missing codepage or helper program, or other error. Apr 24 19:47:17 Krieger emhttpd: shcmd (73): exit status: 32 Apr 24 19:47:17 Krieger emhttpd: /mnt/cache mount error: No file system Apr 24 19:47:17 Krieger emhttpd: shcmd (74): umount /mnt/cache Apr 24 19:47:17 Krieger root: umount: /mnt/cache: not mounted. I have tried to mount the drive as here: But no matter what I try I get "mount: /x: wrong fs type, bad option, bad superblock on /dev/mapper/nvme0n1p1, missing codepage or helper program, or other error." ^the cache is encrypted thats why the device is in /mapper Any other options or is my cache dead? Thanks =\ Diagnostics attached. krieger-diagnostics-20200424-2016.zip Edited April 25, 2020 by MystX Quote Link to comment
JorgeB Posted April 24, 2020 Share Posted April 24, 2020 Filesystem is corrupt, you can try btrfs restore on the same FAQ entry. Quote Link to comment
MystX Posted April 24, 2020 Author Share Posted April 24, 2020 Oh sorry, I read that that was step 2 AFTER you mounted. I will try that and report back after I clear some space off a disk lol Quote Link to comment
MystX Posted April 25, 2020 Author Share Posted April 25, 2020 OK it seems like I've got things mostly sorted. For internet prosperity what I did was follow the guide linked above to restore the cache drive to another drive. Formatted the cache drive, copied everything back over. Unfortunately my libvirt and docker images were still broken. I restored both from a backup. Libvirt was ok after the backup restore but docker was not. Had to delete my docker image, recreate it, then re-install all the dockers from community applications 'previous apps' menu. Thank Johnnie Quote Link to comment
