Upgrading Nodes in Clusters 23

2 Open the /etc/fstab file on the node for editing, and add the /vz entry to it. Make sure

you add the right /vz entry to the file:

a Run the clustat utility to find out the name of the clustered service running on the

active node.

b Search the cluster configuration file (/etc/cluster/cluster.conf) for the

UUID of the device associated with the clustered service, for example:

# cat /etc/cluster/cluster.conf

...

<fs device="UUID=39028daf-0337-4403-9567-84507ac7cb50"

force_fsck="0" force_unmount="0" fstype="ext3" mountpoint="/vz" name="fs-vz-1"

options="" self_fence="0">

...

In this example, the vz-1 clustered service is associated with the device UUID

UUID=39028daf-0337-4403-9567-84507ac7cb50.

c Add the /vz entry to /etc/fstab. For the example above, this string will look like

the following:

UUID="39028daf-0337-4403-9567-84507ac7cb50" /vz ext3 defaults,noatime 0 0

3 Disable the startup of the rgmanager and cman clustering services, and enable the startup

of the vz service:

# chkconfig rgmanager off

# chkconfig cman off

# chkconfig vz on

4 Install Parallels Virtuozzo Containers 4.6 on the node. For detailed information on installing

Parallels Virtuozzo Containers 4.6, see the Parallels Virtuozzo Containers 4.6 Installation

Guide; for upgrade details, see the Upgrading from SWsoft Virtuozzo 3.0 Service Pack 1 (p. 7)

and Upgrading from Parallels Virtuozzo Containers 4.0 (p. 14) chapters.

5 Once the installation is complete, restart the node, and wait for the Parallels Virtual

Automation application to get upgraded.

6 Enable the startup of the cman and rgmanager services, and disable the startup of the vz,

pvapp, and pvaagentd services:

# chkconfig cman on

# chkconfig rgmanager on

# chkconfig vz off

# chkconfig pvapp off

# chkconfig pvaagentd off

7 Open the /etc/fstab file for editing, and remove the /vz entry from it.

Upgrading Passive Nodes in the Cluster

Now that you have upgraded all active nodes in the cluster, you can proceed with upgrading

passive nodes. To upgrade a passive node, do the following:

1 Make sure that the node does not have a /vz partition mounted.

2 Install Parallels Virtuozzo Containers 4.6 on the node (see instructions below). When

installing Parallels Virtuozzo Containers 4.6 on a passive node, pay attention to the

following:

a Use the --clustermode option when installing Parallels Virtuozzo Containers on

passive nodes:

 If you use the vzinstall-linux.bin utility, run this command:
