LVM on-line resizing RHEL AS 3

Keith, thanks for the info.  I have 2 questions:
	1. You can do the same with reiserfs, however it's not supported
in RHEL AS 3.0.  Is XFS "supported"?
	2. Can you provision new boxes with kickstart to setup all
filesystems as XFS?

The way I 'solved' this issue was to use XFS. I can grow the FS live. 
XFS does not shrink but that has not been an issue so far.
