For KVM virtual machines, one of my coworkers worked out a way to live
migrate a VM with its storage to another node on the same cluster with
storage in a different pool. This requires that the VM can be live
migrated to a new host that has access to the same Ceph cluster, and
enough bandwidth
I've used a similar process with great success for capacity management --
moving volumes from very full clusters to ones with more free space. There was
a weighting system to direct new volumes where there was space, but, to
forestall full ratio problems due to organic growth of existing

If we need a live process, where the clients cannot unmpa the volumes, what
do you guys recommend?
We have performed a "live migration"

Hi,
the docs you mentioned also state:
All clients using the source image must be stopped prior to
preparing a live-migration. The prepare step will fail if it finds
any running clients with the image open in read/write mode. Once the
prepare step is complete, the clients can be restarted
