Sun Cluster 2.2 System Administration Guide

4.7.1 How to Repair a Full /var File System

In this example, phys-hahost1 has a full /var file system.

  1. Perform a switchover.

    Move all logical hosts off the node experiencing the problem.

    phys-hahost2# haswitch phys-hahost2 hahost1 hahost2

  2. Remove the node from the cluster membership.

    If you have an active login to phys-hahost1, enter the following:

    phys-hahost1# scadmin stopnode

    If you do not have an active login to phys-hahost1, halt the node.

  3. Reboot the node in single-user mode. 

    (0) ok boot -s
INIT: SINGLE USER MODE

 Type Ctrl-d to proceed with normal startup,
 (or give root password for system maintenance): root_password
 Entering System Maintenance Mode

  4. Perform the steps you would normally take to clear the full file system.

  5. After the file system is cleared, enter multiuser mode. 

    # exit

  6. Use the scadmin startnode command to cause the node to rejoin the configuration. 

    # scadmin startnode
