(sorry for the latency, was on PTO)

The idea would be to deploy and manage cephfs-mirror daemons via cephadm. This would require creating a ceph user to access filesystems in the primary cluster. For now, only a single mirror daemon is recommended/supported. However, going forward one can choose to spawn multiple mirror daemons for concurrency. The interface for this feature is a manager module (`mirroring` plugin).

The developer/user documentation is here: https://github.com/ceph/ceph/blob/master/doc/dev/cephfs-mirroring.rst

Does this help?
