Deploying a Failover Cluster

Configuring Partitions on LUNs

Now that you have created all the necessary partitions, perform the following operations on each

active cluster node:

1 Enable the cluster mode, and stop the vz, parallels-server, vzlmond, and PVA Agent services:

# prlsrvctl set --cluster-mode on

# service vz stop

# service parallels-server stop

# service pvaagentd stop

# service pvapp stop

# service vzlmond stop

2 Move the /vz directory to a temporary directory /vz1 and create a new /vz directory:

# mv /vz /vz1; mkdir /vz

3 Mount one of the shared LUN partitions to /vz, for example:

# mount LABEL=psbm-1 /vz

You need to choose a different LUN partition on each cluster node. Let us assume that you

have a cluster with two active nodes and two shared partitions—psbm-1 and psbm-2. In this

case, if you mount the psbm-1 partition to the /vz directory on the first node, you need to

mount the psbm-2 partition to the /vz directory on the second node.

4 Move all data from the temporary /vz1 directory to /vz, and remove /vz1:

# mv /vz1/* /vz/

# rm -rf /vz1

5 If you plan to use Parallels Virtual Automation to manage your cluster node, also run the

following command:

# /opt/pva/agent/bin/pvacluster.sh private

6 Unmount the shared data storage:

# umount /vz

7 Disable the automatic mounting of the /vz partition on the node start. To do this, remove the

information about the /vz partition from the /etc/fstab file.
