I can confirm that gstripe doesn't have to work only with whole disks.
I am using gstripe on a 5.3-BETA7 system to stripe across two slices
(ad0s2 and ad1s2 on two ATA drives; I am using geom_mirror across ad0s1
and ad1s1).
Actually, I labelled the two stripes using glabel(1) and am in fact
striping the two labelled providers (so I can freely move the disks
around without breaking the stripe).
I do recall some people reporting synchronisation problems using
geom_mirror with SCSI providers (with Pawel providing various patches to
fix things). It's possible the same problems affect geom_stripe
devices.
Cheers,
Paul.
