Before the DB2 DFS Client Enabler is uninstalled, root should ensure that no DFS file is in use, and that no user has a shell open in DFS file space. As root, issue the command:
stop.dfs dfs_cl
Check that /... is no longer mounted:
mount | grep -i dfs
If this is not done, and DB2 DFS Client Enabler is uninstalled, the machine will need to be rebooted.
