2.3 Troubleshooting Cluster and Cluster Node Problems

This section describes solutions to problems that can arise during the day-to-day operation of a cluster and cluster nodes.

2.3.1 How to Repair a Full /var File System

Both Solaris and Sun Cluster software write error messages to the /var/adm/messages file, which over time can fill the /var file system. If a cluster node's /var file system fills up, Sun Cluster might not be able to restart on that node. Additionally, you might not be able to log in to the node.

If a node reports a full /var file system and continues to run Sun Cluster services, use this procedure to clear the full file system.

1. Become superuser on the cluster node with the full /var file system.

2. Clear the full file system.

   For example, delete nonessential files contained in the file system.
