Vinum

[Lewis Thompson]

Hi,

I might be lying to you with my answers.  I'm hoping Greg Lehey or some
other Vinum hacker will point anything I get wrong out though :)

/usr is generally partition e on the slice (at least it is on my
machine).  This means you can set up two Vinum drives using, for
example, ad0s1e.  That way you will be able to mount either disk.

  However, that's not really useful.  You really want to be mounting
/dev/vinum/usr (if that's what you called your volume).  This way Vinum
will handle the synchronization for you.

Yes.  Same for the second disk.  You really want to mount /dev/vinum/usr
as I mentioned above.

Yes.
