BrandonG777 Posted October 19, 2018 Share Posted October 19, 2018 One of my BTRS cache drives seems to have developed a problem over night. Since this drive is part of a mirrored array, can I just format it? (and rebuild it, I assume this would happen automatically?) Quote Link to comment

JorgeB Posted October 19, 2018 Share Posted October 19, 2018 Pool filesystem is corrupt, see here to try and recover your data before re-formatting: https://forums.unraid.net/topic/46802-faq-for-unraid-v6/?do=findComment&comment=543490 Quote Link to comment
BrandonG777 Posted October 19, 2018 Author Share Posted October 19, 2018 (edited) I'm hung up on even getting the FS mounted. Following those instructions it wouldn't mount anything to /x so I went with /mnt/x But I get this trying to mount the first drive /dev/sdc1... mount: /mnt/x: wrong fs type, bad option, bad superblock on /dev/sdc1, missing codepage or helper program, or other error. This should be a mirrored array so I'm assuming that's why I can't mount it so I'm really lost on how to recovery from this. EDIT: Reading further through what you sent I'm realizing the partitions are too corrupted to mount. What would cause something like this? The drives appear healthy.

BrandonG777 Posted October 19, 2018 Author Share Posted October 19, 2018 Recovery in progress... but I'm still really concerned what would have caused this to begin with. Quote Link to comment
JorgeB Posted October 19, 2018 Share Posted October 19, 2018 Would need the syslog from when the issue happened and before rebooting. Quote Link to comment
BrandonG777 Posted October 19, 2018 Author Share Posted October 19, 2018 So now that I've recovered what I can. Format the drives and restore data? Although it looks like I've lost a lot of important stuff due to "looping" Should be in Amazon Glacier but my Cloudberry database was another item that was lost so I'm curious to see how all that plays out.

You can try the last option btrfs check --repair, nothing to lose now, but even if it works recover the rest of your data and reformat to make sure the filesystem starts clean. Quote Link to comment
BrandonG777 Posted October 19, 2018 Author Share Posted October 19, 2018 Now it's saying my /var/log is full. I've deleted stuff but it didn't make any space. root@Veyron:/var/log# du -h 0 ./swtpm/libvirt/qemu 0 ./swtpm/libvirt 0 ./swtpm 0 ./samba/cores/winbindd 0 ./samba/cores/smbd 0 ./samba/cores/nmbd 0 ./samba/cores 0 ./samba 0 ./plugins 0 ./pkgtools/removed_scripts 0 ./pkgtools/removed_packages 0 ./pkgtools 0 ./nginx 0 ./nfsd 0 ./libvirt/qemu 4.0K ./libvirt 108K . I don't understand where it's going. Quote Link to comment

JorgeB Posted October 19, 2018 Share Posted October 19, 2018 Syslog is 0 bytes, so nothing there, reboot and monitor syslog, if it keeps growing grab diags before it gets too big. Quote Link to comment
