Subject: Btrfsck stuck when checking fs roots
Date: Wed, 30 May 2012 11:10:15 +0200 [thread overview]
Message-ID: <CAP4s+CE4z+wG++TV-T1Er9cSoiFfecJN175S0_g7ERRrAV96BQ@mail.gmail.com> (raw)
Hello i've a data partition in my system formated as btrfs, I can
mount the partition without problems, but from time to time I've some
lockings in the disk that force me to reboot the system.
Lately I have been having problems when unmounting the disk too
I have been running for several weeks the kernel 3.3.1, and my
btrfs-tools are version 0.19+20120328-1 (from debian wheezy)
This is the output I am getting from btrfsck, and it always ends up
aborting the "checking fs roots" part.
$ btrfsck /dev/sda1

checking fs roots
Aborted
Is there anything I can do to force a check only in this part while
getting more debug?
