Administering Ceph Block Device mirroring

As a storage administrator, you can perform a range of tasks to manage and maintain the Ceph Block Device (RBD) mirroring environment.

These tasks include:

• Viewing information about storage cluster peers.
• Add or remove a storage cluster peer.
• Getting mirroring status for a pool, image and group.
• Enabling mirroring on a pool, image and group.
• Disabling mirroring on a pool, image and group.
• Delaying block device replication.
• Promoting and demoting an image and group.

These tasks help ensure smooth replication operations and support failover and recovery scenarios in multi-site deployments.
