Because you are moving all disks stored on the domain at once which seems a bit at odds with the iterative upgrade procedure that was first suggested. An export domain would allow him to try a 4.1 DC with just a few VMs at first. Maybe once he is satisfied with the initial upgrade the old data domain could be attached to the new DC to quickly move over the rest of the VMs. > Y. > > >> >> On Wed, May 31, 2017 at 4:08 PM, Charles Kozler <[email protected]> >> wrote: >> >>> 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.
