MicroCeph Squid adds APIs to configure remote cluster awareness and perform RBD replication end-to-end using real Ceph tools: cluster export/import to share credentials, enabling the rbd-mirror daemon, and running promote/demote and resync operations. Replication works at pool or image granularity, supports journaling or snapshot mode with configurable schedules, and intentionally keeps no separate MicroCeph state (it reads Ceph state). Demo uses two VM sites named Delhi and Geneva, shows successful replication though snapshots and state refreshes take noticeably longer.
