According to:
http://lists.ceph.com/pipermail/ceph-users-ceph.com/2016-May/009485.html it
seems not entirely safe to copy an RBD pool this way.
This thread mentions doing a rados ls and the get/put the objects but Greg
mentioned that this may also have issues with snapshots.
Maybe cppool has been
I'm not sure if this is what you need, but I recently tried 'rados
cppool ' to populate a new test-pool with
different properties. I simply needed some data in there, and this
command for me.

Hi Irek & Craig,
Sorry, I misunderstood "RBD mirroring". What I want to do is not like that.
I just want to move all the data from a cluster to another. It can be
achieved by `rados -p get ` for all objects on
cluster A, and then `rados -p put ` on cluster B.
Is there any tool for that?

Hi,
Sorry I gave the wrong feature.
rbd mirroring method can only be used on rbd with "journaling" feature (not
layering).
Sincerely,
Craig Chi

Hi John,
rbd mirroring can configured by
pool.http://docs.ceph.com/docs/master/rbd/rbd-mirroring/
However the rbd mirroring method can only be used on rbd with layering feature,
it can not mirror objects other than rbd for you.

Hi,
I have 2 Ceph clusters, cluster A and cluster B. I want to move all the
pools on A to B. The pool names don't conflict between clusters. I guess
it's like RBD mirroring, except that it's pool mirroring. Is there any
proper ways to do it?
Thanks for any suggestions.
Best,
John Lin
