Volume is mounted on two ServiceGuard nodes

Hey! I'm running a HP ServiceGuard cluster with three nodes. One of the packages was moved (not by me) from one node to another a few weeks ago.

I just noticed that one of the volume groups is still mounted on the old node. Oops! When I run df, less space is used on the old node than the new.

What's the safest way to get rid of it on the old node with no corruption? Off the top of my head I'm thinking something along the lines of:

Code:
mount -oremount,ro VOLUME
umount VOLUME
vgchange -an VOLUME_GROUP

Any tips? Thanks!

NAME
cmhaltcl - halt a high availability cluster SYNOPSIS
cmhaltcl [-f] [-v] DESCRIPTION
cmhaltcl causes all nodes in a configured cluster to stop their cluster daemons, optionally halting all packages or applications in the process. To stop a cluster, a user must either be superuser(UID=0), or have an access policy of FULL_ADMIN allowed in the cluster configuration file. See access policy in cmquerycl(1). This command will halt all the daemons on all currently running systems. If the user only wants to shutdown a subset of daemons, the cmhaltnode command should be used instead. Options cmhaltcl supports the following options: -f Force the cluster to shutdown even if packages or group members are currently running. This will cause the packages and group members to be halted. If a package halt fails, the cluster halt will also fail. -v Verbose output will be displayed. RETURN VALUE
cmhaltcl returns the following value: 0 Successful completion. 1 Command failed. EXAMPLES
Halt the cluster daemons: cmhaltcl AUTHOR
