Hi, 

I'd like to use the mirroring feature 

http://docs.ceph.com/docs/master/rbd/rbd-mirroring/

In my environment I have just one host (at the moment for testing purposes before production deployment).

I want to dispose:

/dev/sdb for standard operatoin

/dev/sdc for mirror 

Of course, I'd like to create two clusters, each cluster with a pool "mypool" and enable mirror.

The final idea is using CephFS for exporting to tape my VMs in consistent state without affecting production OSD /dev/sdb.

http://docs.ceph.com/docs/master/cephfs/createfs/

Anybody has tried something similar? can anybody explain his experience?

Thanks a lot.
