Background: We have a few ceph clusters, each serves multiple Openstack cluster. Each cluster has it's own set of pools.
I'd like to move ~50TB of volumes from an old cluster (we'll call the pool cluster01-volumes) to an existing pool (cluster02-volumes) to later be imported by a different Openstack cluster. I could run something like this...
rbd export cluster01-volumes/volume-12345 | rbd import cluster02-volumes/volume-12345 .
But that would be slow and duplicate the data which I'd rather not do. Are there any better ways to it?
Thanks,
-Brett
