I have created files over 70GB in size on an xfs logical volume under
RedHat 7.1.  This doesn't really help you much with 6.2 or the 2.2 kernel,
I know, but I thought it was worth mentioning.  We've been using xfs on
our head node in production for several months (under quite heavy loads),
and haven't had any real problems with it.
