I have not tried yet, but am planning to experiment and see if it is
possible to *shrink* an XFS filesystem. In the case where I have one
LV that's larger than it needed to be, I'd like to be able to shrink
the filesystem then shrink the LV. Anyone know if that is possible?
If it's not, it should be!

Right. I went with:
part1 500m Linux / (XFS)
part2 1024m Swap
part3 the rest LVM /usr (XFS)
/home
/var
/usr/local
/usr/local/src

I recently read "Linux File Systems", by Moshe Bar (author of Linux
Internals), Osbourne McGraw Hill, ISBN-0-07-212955-7. I also read
"Journal File Systems", Linux Gazette #55,
<URL:http://www.linuxgazette.com/issue55/florido.html>, and some of
the whitepapers I found at <URL:http://oss.sgi.com/projects/xfs/>.
I am very convinced that XFS is the *best* filesystem for Linux. It
is way better than ext3fs for many reasons. From what I gather, it
is also superiour to IBM's JFS, and certainly superiour to Reiserfs.
I've had no trouble with it so far. I've been told that it is
incompatible with LILO; that it starts the filesystem at offset 0
rather than offset 512 like other filesystems? I have not confirmed
this yet. Anyone know? It works great with GRUB.
