The problem with parted is that it deals with the LV, in this case named IDE,as a single partition.
The man page eludes to being able to resize the FS inside of partition. But requires a starting point. Because I have several FS inside my LV, I have no way of knowing where the starting point is.
It has been suggested that I umount my ext3 FS, remount it as ext2, use resize2fs to resize the FS, then remount it as ext3. But Seems like I remember that shifting between the 2 FS is not trivial.
I am continuing to look for definative information.
