[linux-lvm] CLVMD and Locking type 3 initialisation failed

["James Miller" <jimm@simutronics.com>]

Hello everyone,

I'm setting up a cluster and was hoping to get some insight into trouble I'm
having with running clvmd. My cluster seems to be in a good state (2 nodes).
I using Debian Etch, 2.6.18 kernel, and redhat-cluster-modules for 2.6.18.

---------------------------
cman_tool status:
Protocol version: 5.0.1
Config version: 2
Cluster name: alpha1
Cluster ID: 6387
Cluster Member: Yes
Membership state: Cluster-Member

Expected_votes: 2
Total_votes: 2
Quorum: 2
Active subsystems: 3
Node name: hari
Node ID: 1
Node addresses: 209.16.216.121

When I run vgchange -aly I get the following message:
