Hey Eric,

Good point!  We're running CentOS 5, so is the CentOS-Plus repo the way to go?  These servers are all setup from a fairly old base image hence using kmod-xfs, definitely something I'll address.

You reall, Really, REALLY, *REALLY* want to remove kmod-xfs.

RHEL5 has been shipping with supported xfs for what, 2 years now, and that old kmod-xfs
is an ancient, ancient piece of unmaintained, bitrotting code.  Sadly it overrides
the kernel rpm's xfs.ko.  I don't know if this is the root cause of your problem; probably
not, but eventually it will likely be the root cause of some other problem :)
