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.
