jphipps Posted September 28, 2014 Share Posted September 28, 2014 I don't know much about btrfs, but that doesn't look good... Did you have much data on the cache? You may just have to reformat it to get it working again. Quote Link to comment
JustinChase Posted September 28, 2014 Author Share Posted September 28, 2014 not much data, but all my docker appdata files were there Not the end of the world, but no so much fun to set everything up again. Of course, none of this has been any fun. Quote Link to comment
jphipps Posted September 28, 2014 Share Posted September 28, 2014 Since you have to wait to get the array back up, you could see if LT or someone has any ideas before blowing it away. I keep all my app data on the array, but mine is mostly just testing it out. Quote Link to comment
dgaschk Posted September 28, 2014 Share Posted September 28, 2014 Google "btrfs scrub". Quote Link to comment
JustinChase Posted September 28, 2014 Author Share Posted September 28, 2014 doesn't seem to work for me... root@media:/mnt# btrfs scrub start /dev/sdh ERROR: '/dev/sdh' is not a mounted btrfs device root@media:/mnt# mount -t btrfs /dev/sdh /mnt/cachedisk mount: wrong fs type, bad option, bad superblock on /dev/sdh, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so am I doing it wrong?

jphipps Posted September 28, 2014 Share Posted September 28, 2014 You are missing the partition number, it should be sdh1... Quote Link to comment
JustinChase Posted September 28, 2014 Author Share Posted September 28, 2014 hmmm... root@media:/mnt# mount -t btrfs /dev/sdh1 /mnt/cachedisk mount: wrong fs type, bad option, bad superblock on /dev/sdh1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so root@media:/mnt# btrfs scrub start /dev/sdh1 ERROR: '/dev/sdh1' is not a mounted btrfs device Quote Link to comment
jphipps Posted September 28, 2014 Share Posted September 28, 2014 Maybe if you dump the formating you could see what is there. Try a : fdisk -l /dev/sdh My btrfs cache volume is showing a id of 83 for the 1 partition. Quote Link to comment
JustinChase Posted September 28, 2014 Author Share Posted September 28, 2014 Interesting... root@media:/mnt# fdisk -l /dev/sdh Disk /dev/sdh: 500.1 GB, 500107862016 bytes 1 heads, 63 sectors/track, 15504336 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdh1 64 976773167 488386552 83 Linux Quote Link to comment
jphipps Posted September 28, 2014 Share Posted September 28, 2014 Looks like the btrfs wiki has a page with a few things to try: https://btrfs.wiki.kernel.org/index.php/Problem_FAQ There is one for mounting as recovery to try to get data off. I think you just add a "-o recovery" Quote Link to comment
JustinChase Posted September 28, 2014 Author Share Posted September 28, 2014 hmmm, I thought I'd already tried that, but in trying it again just now, it worked!! I'm currently copying from the cache to an array disk. Fingers crossed it finishes okay. thanks again for all your help!! Quote Link to comment
jphipps Posted September 28, 2014 Share Posted September 28, 2014 Cool, glad that worked... From my experience, I am not really a fan of BTRFS... Quote Link to comment
JustinChase Posted September 28, 2014 Author Share Posted September 28, 2014 After this, me neither. I'll convert my cache to XFS when I end up having to reformat it, since docker doesn't need it anymore. It will be late tomorrow before the copying is finished, assuming it finishes without issue.

IsSidha Posted November 30, 2014 Share Posted November 30, 2014 very weird thing.... my cache drive showed as unformatted at every reboot (2 drives).. after formatting it works well until reboot after another reboot and again an unformatted cache drive i decided to do a "new config" and reassign the drives after reassigning the drives they were no longer unformatted and the data was present after another reboot the docker was alive and the apps running :o Quote Link to comment
