2) If above is always to be an issue .. can I make default VM
deployment be a dedicated gluster volume (my case is 1TB SSD with VDO
in each server) such that rebuild of engine layer can just slurp back
in the VMs from that volume.
It is highly recommended (well actually all devs will
say required)
that you have a separate datastore for the HostedEngine and no VMs
should be hosted there.
That's why the cockpit deployment is creating a dedicated volume.
