[Cialug] Xfs for centos

[Nathan C. Smith]

Anybody using xfs (filesystem as opposed to x font server) on Centos?  (I think Centos 4.4 or 5.2 or somesuch).  How is the support?

There are several packages, how do I know which xfs support to use from yum search xfs?

kmod-xfs.i686
kmod-xfs-smp.i686
kmod-xfs-hugemem.i686
Etc.

"Yum install xfs" didn't do anything so I probably have to pick one.
The reason I was looking at XFS was for support on a really large filesystem.  Should I just stick with ext3 for safety's sake?

Thanks.
