Date: Sat, 4 Nov 2017 20:08:37 +0100 [thread overview]
Message-ID: <e0476253-d0e6-8b0d-df01-28c2f7fcbe77@profihost.ag> (raw)
Hello,
after a power failure i have a btrfs volume which isn't mountable.
dmesg shows:
parent transid verify failed on 181846016 wanted 143404 found 143399
If i run:
btrfs check --repair /dev/mapper/crypt_md1
The output is:
parent transid verify failed on 181846016 wanted 143404 found 143399
parent transid verify failed on 181846016 wanted 143404 found 143399
