OK, I've read up on the linux-lvm & linux-xfs mailing lists about the
introduction of XFS' version 2 log format on 6/18/02.  I'm just a little
slow, and I'm uncertain about how I need to set up the FS to avoid the
misalignment problems Joe mentioned.  Feel free to flame me if I should've
posted to linux-xfs, instead.

Will the following work:
mkfs -t xfs /dev/vg0/lv0 -l internal,version=2,sunit=1
If not, does anyone have an example 'mkfs.xfs -l version=2,su=X' command
that would give me a filesystem with the appropriate alignment?
