Does anyone know what the current status of pvmove is regarding its use on clustered volume groups in RHEL 5.4? The official RH documentation for CLVM states the following:
“Because the pvmove command uses mirroring, it is not cluster-aware and needs exclusive access
to a volume. For information on activating logical volumes on individual nodes in a cluster, see
Section 4.8, “Activating Logical Volumes on Individual Nodes in a Cluster”.”
But there are also steps on enabling the cmirror kernel module, which implies you can use mirroring on a CLVM setup.
