There is a really good LVM HowTo here http://www.ibiblio.org/pub/Linux/doc...LVM-HOWTO.html
The bottom line about resizing ext3 logical volumes is that it is easy to make them bigger, but difficult to make them smaller. In theory, the resize2fs command can reduce the size of the ext3 filesystem, but in practice, you will get a fatal error message regarding the new target size when you try to reduce the ext3 filesystem.
RedHat has really screwed everyone who uses the installation default LVM partitioning scheme, because it fills the volume group with logical volume(s), but does not provide tools for reducing the ext3 logical volumes to allow others to be created or enlarged. I anticipate that these tools will appear at some future date, presumably before the release of RHEL5. But, for now, you're screwed.
You hit the nail on the head....
By the way, it doesn't look like RH has addressed this in RHEL5....still screwed....well not totally screwed i guess.....the work around above does work
