Prasanna Kumar Kalever e7d8834149 rbd: enabe journal based mirroring
Journal-based RADOS block device mirroring ensures point-in-time
consistent replicas of all changes to an image, including reads and
writes, block device resizing, snapshots, clones, and flattening.

Journaling-based mirroring records all modifications to an image in the
order in which they occur. This ensures that a crash-consistent mirror
of an image is available.

Mirroring when configured in journal mode, mirroring will
utilize the RBD journaling image feature to replicate the image
contents. If the RBD journaling image feature is not yet enabled on the
image, it will be automatically enabled.
