Hi !
I have a virtual server (Xen) which very frequently hangs with only
this error in logs :

In fact I haven't enough memory to run it (8GB of RAM only, with a 2*3TB
FS in mirroring, btrfs mirroring).

Hi,
I still have kernel BUG with recent btrfs fixes :

Hi,
I have a btrfs partition which throw kernel BUG, even with linux
3.17-rc3 (I tried 3.14.16, 3.16.1 and 3.17-rc3 kernels) :

Then, 30 minutes later there is no change, so I suppose it's "frozen".

Hi,
I have a btrfs volume that I can't mount RW (but I can mount and use it
RO).
So, at boot time, the partition is mounted RO
(defaults,noatime,compress-force=zlib,nossd,ro) :

Feb 1 22:30:12 frozen kernel: [8.650878] device fsid
Hello,
I had an umountable FS, no kernel oops, just "mount /backup" which still
running after hours, without throwing any IO to disk.

the "ro" option works

Hi,
on one system I have a "frozen transaction" since more than 24 hours,
without any IO.
I can't umount the partition, delete a snapshot or write anything.
I try to reboot the system, but the problem is still present.
Here the "frozen transaction" :

Ok, thanks. So I will wait for the 3.5.3 kernel (since 3.5.2 don't seem to have
any btrfs fix).

Hi,
I have a strange problem with a btrfs partition : after an error, btrfs was
forced readonly.
So I try to umount it, to launch btrfsck, but it doesn't work :
root! sofia:~# umount /backup/
root! sofia:~# btrfsck /dev/vg-sofia/backup
/dev/vg-sofia/backup is currently mounted. Aborting.
