Yes. If you have clvm on one node on a cluster then it needs to be on ALL nodes of the cluster - you can't have an isolated node that is also part of the CMAN cluster.
I had kind of figured this out. If what you mean is "can I have a non-clustered Volume Group alongside cluster volume groups", then the answer is "yes". There is a flag on the VG that indicates whether it is clustered or not. activated with vgchange -cy, deactivated with vgchange -cn. You can't mark individual LVs within a VG as clustered/non-clustered though. That wouldn't make sense.
Well, I think I have a bug to report. When I create a vg and mark it as not clustered, I get locking errors when working with its LVs.
