NetBSD has not has a 2GB filesystem limit for ... several years.  And
NetBSD already comes with a RAID implementation called RAIDframe
(originally developed at CMU as a RAID research tool).

Here's a snippet from my AlphaServer 1200:

Hm, my example above shows the reboot after a crash (unrelated to RAID :-),
note that the `unclean' components had partity reconstruction done while
the file system was totally usable (i.e. the file system was fsck'd then
mounted and the system came up multi-user while the parity reconstruction
was still happening).

I've been very happy with RAIDframe.
