.Block Device mirroring is now supported
The RADOS Block Device (RBD) mirroring feature has been added to the Red Hat Ceph Storage 2. RBD mirroring is a process of replicating Ceph Block Device images between two peer Ceph Storage Clusters. The mirroring is asynchronous, crash-consistent, and serves primarily for disaster recovery.
To learn more about RBD mirroring, see the https://access.redhat.com/documentation/en/red-hat-ceph-storage/2/single/block-device-guide/#block_device_mirroring[Block Device Mirroring] chapter in the https://access.redhat.com/documentation/en/red-hat-ceph-storage/2/single/block-device-guide/[Block Device] guide for Red Hat Ceph Storage 2.
