Subject: btrfs fails to mount after power outage
Date: Wed, 11 Apr 2018 16:33:21 +0100 [thread overview]
Message-ID: <CAG4vCreOmBdsPT84ajozGb4XV83+Fc-joyUqXgizutPah0VrrA@mail.gmail.com> (raw)
My btrfs laptop had a power outage and failed to boot with "parent
transid verify failed..." errors. (I have backups).
I couldn't rw mount on a live disk, but could ro mount. I tried btrfs
scrub and then btrfs check --repair to no avail. However, btrfs rescue
zero-log _did_ work; the drive can be rw mounted and the machine boots
fine again.
Although there doesn't appear to be an immediate data loss, there's
still a transid error during boot. "BTRFS error (device dm-0): parent
transid verify failed on 115490816 wanted 339949 found 340182".
If I umount and re-run btrfs check, I'm given further transid errors
and pages of "inode [n] errors 2001, no inode item, link count wrong".
What steps should I take now?
btrfs progs 4.15
kernel 4.15.15
NVMe drive
