Bug ID 4362925

Problem Summary:

nodeA# scshutdown -g0 -y
scshutdown: Unmount of /dev/md/sc/dsk/d30 failed: Device busy.
scshutdown: Could not unmount all PxFS filesystems.

The Networker packages were bundled and installed during the Oracle installation. Therefore, the nsrmmd daemon is running and mounting to the /global/oracle directory, which prevents the unmount of all cluster file systems.

nodeA# umount /global/oracle
umount: global/oracle busy
nodeA# fuser -c /global/oracle
/global/oracle: nodeA# umount /global/oracle
umount: global/oracle busy
nodeA# fuser -c /global/oracle
/global/oracle: 335co 317co 302co 273co 272co
nodeA# ps -ef|grep 335
 root 335 273 0 17:17:41 ?       0:00 /usr/sbin/nsrmmd -n 1
 root 448 397 0 17:19:37 console 0:00 grep 335

This problem occurs during Sun Cluster shutdown when the shutdown tries to unmount a cluster file system that the process nsrmmd is still referencing.

Workaround: Run the fuser(1M) command on each node to establish a list of all processes still using the cluster file systems that cannot be unmounted. Check that no Resource Group Manager resources have been restarted since the failed scshutdown(1M) command was first run. Kill all these processes with the kill -9 command. This kill list should not include any processes under the control of the Resource Group Manager. After all such processes have terminated, rerun the scshutdown command, and the shutdown should run to successful completion.
