7.10 GPFS shutdown

< Day Day Up >

You can shut down all GPFS file systems and daemons using the mmshutdown command. This command umounts all GPFS file systems mounted on the localhost and shuts down all GPFS-related daemons.

If you want to shut down GPFS on a local node only, issue the mmshutdown command without any parameters, as shown in Example 7-39.

Example 7-39: Shut down a local node

 [root@storage001 bin]# mmshutdown Thu Nov 23 23:08:16 CDT 2002: mmshutdown: Starting force unmount of GPFS file systems Thu Nov 23 23:08:21 CDT 2002: mmshutdown: Shutting down GPFS daemons 0513-044 The mmfs Subsystem was requested to stop. Shutting down! 'shutdown' command about to kill process 30872 Thu Nov 23 23:08:23 CDT 2002: mmshutdown: Finished [root@storage001 bin]#

If you want to shut down all GPFS nodes in the nodeset, issue the mmshutdown command with the -a parameter. Because you can run GPFS administrative commands from any node that belongs to the GPFS cluster, Example 7-40 shows the mmshutdown -a being executed in node001.

Example 7-40: Shut down all nodes in the nodeset
