You fill up your RAID storage array and need to add more disks,

a new partition but that's not always an option, i.e. large databases
You can merge the two slices to make a larger RAID set, but then you
can't expand the HFS+ partition to fill the larger device.
I guess you _might_ be able to pdisk the partition larger. Less scary
might be a union mount in fstab.
XSan, with it's storage pools, just hides all of this from the end
users.
