I couldnt find a definitive on this so I would like to inquire here I have gluster on my storage backend exporting the volume from a single node via NFS I have a DC of 4.0 and I would like to upgrade to 4.1. I would ideally like to take one node out of the cluster and build a 4.1 datacenter. Then live migrate VMs from the 4.0 DC over to the 4.1 DC with zero downtime to the VMs Is this possible? Or would I be safer to export/import VMs? Thanks! _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users
