Sun Cluster System Administration Guide for Solaris OS

Repairing a Full /var File System

Both Solaris software 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.

ProcedureHow to Repair a Full /var File System

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. Refer to Viewing System Messages in System Administration Guide: Advanced Administration for more information.

This procedure provides the long forms of the Sun Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix A, Sun Cluster Object-Oriented Commands.

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

  2. Clear the full file system.

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