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,
That simply does not make sense to me. How can all data be gone and the
FS just mount cleanly.
Can you try to format the RBD with EXT4 and see if that makes any
difference.
Could you also try to run a "sync" prior to pulling the power from the
host to see if that makes any difference.
