Hallo,
"never change a running system" ...
For some months I run btrfs unter kernel 3.2.5 and 3.2.9, without
problems.
Yesterday I compiled kernel 3.3.4, and this morning I started the
machine with this kernel. There may be some ugly problems.
Copying something into the btrfs "directory" worked well for some files,
and then I got error messages (I've not copied them, something with "IO
error" under Samba).
Rebooting the machine with kernel 3.2.9 worked, copying 1 file worked,
but copying more than this file didn't work. And I can't delete this
file.
That doesn't please me - copying more than 4 TBytes wastes time and
money.

==========================================================
The 3 btrfs disks are connected via a SiI 3114 SATA-PCI-Controller.
Only 1 of the 3 disks seems to be damaged.
==========================================================
Ca I repair the system? Or have I to copy it to a set of other disks?
Viele Gruesse!
Helmut
