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" :
$ ps auxw | grep btrfs | grep D
root 1835 0.0 0.0 0 0 ? D Oct08 0:13
[btrfs-cleaner]
root 1836 0.0 0.0 0 0 ? D Oct08 0:01
[btrfs-transacti]
root 2633 0.0 0.0 0 0 ? D Oct08 0:00
[flush-btrfs-1]
The partition is mounted with this options :
# mount | grep btrfs
/dev/mapper/vg--sofia-backup on /backup type btrfs
(rw,noatime,compress-force=zlib,nossd)
The disk is near full :
# btrfs fi df /backup/
Data: total=482.68GB, used=480.89GB
System, DUP: total=32.00MB, used=72.00KB
System: total=4.00MB, used=0.00
Metadata, DUP: total=10.12GB, used=8.82GB
But one of the last actions was the removing of some big subvolumes
(near 50GB).
There is no error in logs, the frozen transaction was started from a
3.5* kernel (from GIT), and the system is now running on a 3.6.1 kernel
(vanilla).
Is there something I can do to solve that problem ?
Thanks,
Olivier
