Thanks Jan, for the tip and everybody for the rest of the responses. 
  Further investigation reminded me where I was stumped the first 
time I tried to format an XFS partition.  The default FC2 
installation does not have the xfsprogs package, so no mkfs.xfs 
command or xfs utilities.

Apparently the easiest way to use XFS with FC2 is to feed the "linux 
xfs" parameter at install time but to hold off on actually making 
the filesystem until later.  Then:

# mkfs.xfs -i size=512 /dev/hda<n>


This is due to reduced performance and the amount of space wasted by 
SELinux if the default inode size of 256 bytes is used.

Does anyone have any info on tuning xfs and/or ext3?  None of the 
default settings on my filesystems have been changed at all.

Two reasons:  1) I'm on a 56k net connection so obtaining a new 
distro is relatively inconvenient;  and, 2) the accelerated life 
cycle of fedora is a little bit faster than ideal for me.  I'm 
trying to increase my ratio of time spent on real work (tm) to 
administration and troubleshooting.

Upgrading to a new version of a distribution usually solves some 
problems while introducing new ones and I'm in the process of 
running down most of the major rough spots in the FC2 installation 
on my production machine.
