The error is so clear, you have lvm configured in exclusive mode, that means you can't access to your vg from more then one node at a time

Hi All, I am having a problem using pvmove during some testing with Red Hat
Cluster using CLVM on RHEL 6.2. I have 3 nodes which are ESXi 5u1 VMs with the
'multi-writer' flag set for the shared vmdk devices. I keep getting locking
errors during the pvmove. Everything else seems to be working great as far as
CLVM goes. Searching through the list archives and consulting the manuals it
looks like all you need is to have cmirrord running. The RHEL 6 manual
mentions cmirror-kmod which doesn't seem to exist anymore. Is there still a
kernel module on RHEL 6? I am standard clvm with ext4 in an active/passive
cluster. Anyone know what I am doing wrong? Below is my lvm config and my
cluster config. Thanks in advance.
