Automatically unmount Filesystems before reboot.

Hi everyone,

I was wondering:

How can it be accomplished, that all non rootvg filesystems are being automatically unmounted before System reboots when issuing the "reboot" command ?

I understand there's the rc.shutdown file but this seems to work with "shutdown" command only and NOT with "reboot" command. :-(

Any suggestions ?

Best Regards,
Thomas Schmitt
 
Hi,

unmount of all filesystems are part of each reboot/shutdown. If a process keeps an filesystem open, it will be forcefully unmounted.

Hi NoLogic001,

IBM told us we'd have to take care of that ourself ...

Problem is: On one machine certain filesystems are always corrupted after a reboot and an fsck has to be performed. IBM came up with the hint that those filesystems are not being unmounted cleanly during a reboot and we were supposed to do it manually before rebooting the System.

However: This is something that is easily forgotten over the time. So I was hoping for an automated solution.

Regards,
Thomas
 
No see, what they mean is that there is a process that keeps the filesystem open and when you reboot it is done forcefully(no cleanly) and ends up corrupting the filesystem.

You need to find the process that is keeping the filesystem open and kill it before a reboot. It's most likely and application or database that is not stopped properly before the actual reboot.

you can do a ps -ef grep <filesystem name> to find the culprit or use the command fuser.

fuser -u /tmp
