The only safe way to make a filesystem smaller is to back it up, delete the filesystem, recreate it at the smaller size, and then restore the backup. Do you not have any disk space that isn't being used by a filesystem?

I have only temp as a free filesystem but i think that is reqd by some application installation, is it not possible to create a swap using some space from the existing filesystem as we do in solaris something like by creating a file with 100mb using mkfile and then again adding it to swap using swap -a <filename>... is there a way similarly on Hp-Ux?.. thanks

No.

I thought you can create file system swap(not device swap) dynamically without destroying the existing file system?

I can't remember the command how to do it. May be it's swapon or something.

dreamer, it appears you are right, at least from what I see in man swapon. I've never done it this way.

You didn't install the man pages?

Go to this website and search for swapon:
