Need a compressed file system temporarily

Tue Oct 6 15:14:22 UTC 2009

I have RHEL 4 or 5 with standard installation. I need a compressed file system temporarily to store an Oracle data pump export file. What's the easiest solution? Oracle data pump does not support a sequential device as its output so I can't pipe the output to gzip or compress. Creating the dump file on an internally compressed file system is the best I can think of. Thanks.
