Is this really mirrored ? I want a mirror, not a concatenated drive !
I want RAID 1.

And - this isn't very optimal for a user to create.

I do not want to calculate the sd offset size. I'm not a
beginner with vinum, but I really do not want to do this.

IMHO there should be a way for vinum to add this dynamically
like:

vinum sd-add -d 0 -n var -l 1GB
vinum sd-add -d 0 -n docsis -l 6GB
vinum sd-add -d 0 -n docsisvar -l end

A program under unix does not have to be very cryptic,
it also has to be userfriendly.

Martin
