Hello,
I have a filesystem (three disks with no raid) that I can still mount
ro, but I cannot check or scrub it.
In dmesg I see:
[So Aug 28 11:33:22 2016] BTRFS error (device sde): parent transid
verify failed on 22168481054720 wanted 1826943 found 1828546
[So Aug 28 11:33:22 2016] BTRFS warning (device sde): Skipping commit of
aborted transaction.
(more complete at the end of this mail)
What I did up to now in order to recover:
- mount ro,recovery
(http://marc.merlins.org/perso/btrfs/post_2014-03-19_Btrfs-Tips_-Btrfs-Scrub-and-Btrfs-Filesystem-Repair.html)
that works.
btrfs check will lead to "Couldn't open file system"
root@homeserver:~# btrfs scrub start /mnt/test
scrub started on /mnt/test, fsid a8af3832-48c7-4568-861f-e80380dd7e0b
(pid=18953)
root@homeserver:~# btrfs scrub status /mnt/test
scrub status for a8af3832-48c7-4568-861f-e80380dd7e0b
scrub started at Sun Aug 28 12:02:46 2016 and was aborted after
00:00:00
total bytes scrubbed: 0.00B with 0 errors
First thing to do now is probably to check the backups. But is there a
way to repair this filesystem?
Besides this: What could be the reason for this error?
Scrubs were regular and good. There was no power loss and also smartctl
looks fine on all three drives.
Greetings,
Hendrik
