Deploying a Data Sharing Cluster

This command creates the clustered service pservice1; enables its autostart (-a 1);

configures the service to run exclusively (-x 1); sets its recovery policy to restart (-r

restart); assigns IP address 10.10.10.200 to the service (-i 10.10.10.200); and

associates the service with the failover domain domain1 (-d domain1) and the script

vzservice (-s vzservice).

Configuring the Cluster

Once you create the cluster configuration, distribute the configuration file

(/etc/cluster/cluster.conf) to all cluster nodes, and start the cman service on each cluster

node one after another.

# service cman start

Once the cman service successfully starts on all cluster nodes, complete the following tasks on

each node:

1 Start the gfs2 service:

# service gfs2 start

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

# mv /vz1/* /vz/

# rm -rf /vz1

3 Start the rgmanager service:

# service rgmanager start

4 Configure the clustering service to start in the default runlevel. For example, if your system

default runlevel is set to 3, you can enable the service by executing the following commands on

each of the cluster nodes:

# chkconfig --level 3 cman on

# chkconfig --level 3 rgmanager on

Once you perform the operations above, use the clustat utility (you can run it on any cluster

node) to make sure that all the services have been successfully started. If they have not, investigate

the cluster logs stored in /var/log/messages by default. Keep in mind that the information you

are looking for may be placed on different servers in the cluster.

Configuring Parallels Virtual Automation

If you plan to use the Parallels Virtual Automation application for managing your cluster nodes:

1 On each cluster node, start the PVA Agent services, and configure them to automatically start

when you restart the nodes:

# service pvaagentd start

# service pvapp start

# chkconfig pvaagentd on

# chkconfig pvapp on

2 Log in to the Parallels Virtual Automation Management Node.

3 Register all cluster nodes one after another. To register a node, use its IP address.
