cephfs-mirror – 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.


-c ceph.conf, --conf=ceph.conf

Use ceph.conf configuration file instead of the default /etc/ceph/ceph.conf to determine monitor addresses during startup.

-i ID, --id ID

Set the ID portion of name for cephfs-mirror

-n TYPE.ID, --name TYPE.ID

Set the rados user name (eg. client.mirror)

--cluster NAME

Set the cluster name (default: ceph)


Run in foreground, log to stderr


Run in foreground, log to usual location


cephfs-mirror is part of Ceph, a massively scalable, open-source, distributed storage system. Please refer to the Ceph documentation at http://ceph.com/docs for more information.
