Linux Clustering With Csm and Gpfs

6.9 Uninstalling CSM

If you want to completely remove CSM from all the nodes in your cluster and the management node, use the uninstallms command:

# uninstallms -u

This will:

• Remove the CSM code from the cluster nodes by running rmnode -u -N AllNodes.

• Uninstall CSM rpms from the management node.

• Delete the CSM logs from the management node.

The uninstallms -u command will not remove the CSM configuration from /etc/opt/csm, the CD images from /csminstall, or the csm.core fileset from the management node. These must all be uninstalled manually, as shown in Example 6-38.
