Hi,
I am trying to do a script which will show disk usage for filesystems within a vg.

This needs to exclude any additional filesystems which might be mounted over a dir within a filesystem.

an example:
/usr is mounted on /dev/hd2 within rootvg
If /usr/another is an additional mount point for some other lv, I would like this excluded.

problem I am having is that du includes all dirs exist below /usr, is there a way to restrict this to dirs within its own mount point and not additional mount points?

Cheers for any info...

I believe you are looking for the command df.
use
df mountpoint

$ man du

-x, --one-file-system
skip directories on different filesystems

Aye, I re-read the man page and found the -x yesterday afternoon, seems to do the job, just certain filesystems on a df -k show a different usage than the du -x, any reason you can think of?

Cheers for the reply.....

try du -kx
