Anyway, I'm getting an off-site name server, so that shouldn't happen again. >>> I am trying to setup vinum on my 4.3 system for the first time and >>> need some help as I'm not understanding this very well. >>> Specifically, I have 3 4.3G drives with a 100M root partition on the >>> first and a 192M swap partition on the other two.

But if you only want one volume, you'd have space left over if the drives weren't all the same size. The trick way to turn /usr into a Vinum volume is to make swap 265 sectors longer when installing, then place /usr immediately after swap. After installation, reboot in single user mode, shorten swap by 265 sectors and make an overlapping Vinum drive start there. The real /usr will then be at the beginning of the subdisk space, so you just need to define a plex with the same location as the /usr partition. I'll write this up in more detail some day.
