Hi all,

Any ideas how can I resolve my issue? Or where the problem is?

Let me describe the issue.
Host boots up and maps RBD image with XFS filesystems
Host mounts the filesystems from the RBD image
Host starts to write data to the mounted filesystems
Host experiences power failure
Host comes up and map the RBD image
Host mounts the filesystems from the RBD image
All data from all filesystems is lost
Host is able to use the filesystems with no problems.

Filesystem is XFS, no errors on filesystem,

Kernel 3.5.0-19-generic
