maybe you need to specify block size (bs= see the mount manpage) when
mounting or...
the man page says it can only be as big as pagesize. Check your page
size `$ getconf PAGE_SIZE`, maybe that's the problem.

seems to show after linux-2.6.22 you should be able to ignore page size
when mounting XFS volumes.

Good luck
