Hi Folks,

I am trying to umount /backup filesystem so that I can create a large enabled filesystem but I keep getting error message saying cannot umount /dev/lv01: The requested resource is busy.

The /backup filesystem within the lv01 logical volume is virtually empty so I do not understand what it means 'resource busy'?

Is there any other way of finding out the cause of this roblem?

Many thanks

Katherine
 
Are you in the /backup dir while trying to unmount, which is my usual trick.

cd /
umount /backup

Hi,

usually appens that someone, probably you, has a window
open over /backup directory.
Use pwd and cd to exit from this simple situation.

More in general ( the above case reenters in this one)
there is a process that has its "feet" in one directory
below /backup.

In this forum there are a lot of posts explaining use
of commands fuser and lsof.
See which is the cause and, if you can close( gently ) it.

The last res. is to reboot the system, try to not use it.

Bye.
