The FS_RAID filesystem type is called (in OpenBSD disklabel for

i386) just plain RAID. Type "RAID" at the prompt for filesystem type.

(Side note: on e.g the platform sparc64 you use "4.2BSD", not "RAID")
Then go on and follow the article again. There are other articles like

that out there, I followed some other that was clearer on that point...

Nowdays I tend to improvise. I prefer to retain the whole base

installation that was used to build the raid-aware kernel (if I have

the diskpace) in case of disaster. Then one does not have to start

with a broken mirror - it can be created whole at once.
By the way, I recall rumours about some other RAID implementation coming

in OpenBSD 4.2. Does anyone know, just rumours?
