Ceph daemon for mirroring CephFS snapshots




cephfs-mirror is a daemon for asynchronous mirroring of Ceph Filesystem snapshots among Ceph clusters.

It connects to remote clusters via libcephfs, relying on default search paths to find ceph.conf files, i.e. /etc/ceph/$cluster.conf where $cluster is the human-friendly name of the cluster.

Connect to specified monitor (instead of looking through ceph.conf).
