Can't umount /var?

Jon Mattatall — Thu, 30 Aug 2001 11:37:30 GMT

Hi there -
On HP-UX 11.00, I've lvextended /var and am now trying to extend the fs to the new size. However, when I:
shutdown -y 0
umount /dev/vg00/lvol8
it says "Device in use" - if I reboot to hpux -lm, and try to umount, the message is "requires block file"
I'm fairly new to this, but how can I determine what's in use?
(ps -ef |grep var shows nothing, but I'm not sure if it should)

Jon

Oops - I'm using a Web Console to a remote location - that may have some impact as well

Hi

use fuser to see which user are working or open a file in the /var .

you dont need to boot with lm option but to boot with isl>hp-ux -is
to boot to a single user mode and then do you action on the /var .

you can also active the vg if you are booting with lm .

the Web Console dont have any effect on this .

tell me if you need more help

Hi Jon,

For a mounted filesystem, use:

fuser -cu /var

to see who is using it.

However, the extendfs will need to be done in single-user mode, since a number of multi-user processes will be using /var, e.g. the logging tools.

Rgds, Robin.

Good ideas, but -
when I boot with hpux -is and try
umount /dev/vg00/lvol8
I get - "umount: cannot umount /var : Block device required"

Doesn't that mean a disk?

I do not grok this at all, 30 secs before this I umounted, extendfs, mounted lvol7 without a problem.

Would this have a chance?
shutdown -y 0
fuser -k /var
umount ......

Forgive me, my error...

I forgot that /var ISNT MOUNTED at this point

Eran, you were right on the money

Thanks very much
Jon

Hi Jon,

Can you show us what the output of the following commands shows:

ls -l /dev/vg00
mount -p

Rgds, Robin.
