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.
