Full Discussion: Filesystem unable unmount
Operating Systems AIX Filesystem unable unmount Post 302965585 by hicksd8 on Sunday 31st of January 2016 12:08:57 PM
Old 01-31-2016
I'm not an AIX specialist so I'm only talking in generic Unix terms. I appreciate that some of the points I'm about to make are blindingly obviously but I'll mention them anyway just for completeness.

Points to check are:-

If there is an Oracle database or journal file on the filesystem, has the Oracle database been shutdown before the umount is tried?

Are there any shares published from that filesystem (eg, NFS handle) that a remote node has hold of?

Is it the server end of a client/server configuration running some other protocol that the remote client is holding open?

As already mentioned, are there any other filesystems mounted beneath directories on the filesystem?

Ensure that you yourself are not in any directory on the filesystem when you attempt the umount as that will make it 'busy'.

What error to do get when it refuses to umount the filesystem?????

       this event as an informational signal, services and tasks started or stopped by this event will do so in parallel with other activity.

EXAMPLE

       A service that wishes to be running once filesystems are mounted might use:

	      start on filesystem
