Running clvm on part of the cluster

Hello there.

I need your help to solve some issues I met.

I use redhat-cluster (as part of Proxmox VE) in our virtualization
environment.

I have several servers with SAN storage attached and CLVM managed
volumes. In general it works.

Today I had to attach one more box to Proxmox instance and found
blocking issue:

this node joined cluster, proxmosFS started and everything is ok with
this host. But it does not have SAN connection, so I didn't start CLVM
on it. And when I try to do some lvm-related work on other host I got
"clvmd not running on node <node-without-clvm>"
and locking failed.

Ok, I thought, and started CLVM on that host...

and locking still fails with 
Error locking on node <node-without-clvm>: Volume group for uuid not
found: <id>


So my question is:

How to handle situation, when only part of cluster nodes has access to
particular LUN, but need to run CLVM and use CLVM locking over it?
