Help Needed

We have this root filesystem which is 95% full and needs to be trimmed down. I am not the root owner but need to find out which files are eating up the space avoiding the other filesystems ( diff mount points like /var etc) which are mounted on there own filesystems. How to achieve this. "du -sk * |sort +nr " is taking a lot of time and trying to consider other fs also . One more thing if I am not root then can find out the space available in a particular dg ( disk group ) , specially the rootdg.

thanks,
hunki

Look for things in /etc

You really need root - as the average user won't be able to transverse all file systems.

I got this excellent script (off here I think) that tells you how many MB/GB each directory is taking up. It gives the top 20 in a directory...of course, you can modify it to give you the top 30, 40...100 whatever you want. The script is an attachment.

The syntax is

./top20.sh /filesystem

You can exclude the other file systems from your du by changing the s to x:
# du -xk /

Even better, sort the output:
# du -xk / | sort -k n1

It will still take some poking around, but this will help you narrow your search.

You may want to do a search for core files:
# find / -type f -name core -xdev
(the -xdev should keep you from wandering outside the root FS)

Hope this helps....

Sincerely thought you don't do it. If you don't have root permission, you shouldn't do it.

Thanks Coolmar / Jim. 10 points each.
