Hello I have to migrate the Gluster volumes from an old oVirt cluster to a newly built one. I looked into migration strategies, but everything that Red Hat recommends is related to replacing old bricks. In a testing environment I created two clusters and wanted to migrate one volume after the other. Unfortunately that fails because a node cannot be part of two clusters at the same time. The next thing I see, is to recreate the volumes on the new cluster, then constantly rsync the files from the old cluster to the new one and at a specified point in time make the cut over where I stop the applicaiton, do a final rsync and remount the new volume under the old path. Is there any other, nicer way I could accomplish migrating a volume from one Gluster cluster to another?
