Hallo, linux-btrfs,
next problem ...
I had tested the next possible steps after deleting a partition.
btrfs device delete /dev/sdb1 /mnt/btr
worked well.
Then
btrfs scrub start /mnt/btr
and all was dead. Really dead. No access via keybord, no access via SSH.
Restarted the machine, mounted the btrfs bundle, then again
btrfs scrub start /mnt/btr
and the same reaction. Dead.
No entry in "/var/log/messages", no entry in
"/var/log/warn".
Viele Gruesse!
Helmut

And a patch from Chris fixed that. Arne had two patches to test that he thought might fix the lock up hard issue, but I didn´t need those.

Then possibly after some kernel upgrade, I did a btrfs filesystem balance on it and then the scrub didn´t die immediately, but got stuck. Did you try whether a balance works? Maybe 3.2.10 oder 3.2.11 contains some related fixes? But then I don´t think that the Debian Wheezy kernel already has 3.2.10 or 3.2.11.

Cause I didn´t do anything specific to fix the hard lock up issue. The getting stuck issue Chris Mason fixed by with casting patch.
