I'm trying to setup a mirrored volume, but haven't gotten too far.
A freshly installed 4.7-RELEASE, with
ad0s1{a,b,e} - /, swap, /usr
da{0,1}s1{b,e} - swap, <future-mirrored-var>
right now, I have /var on da0s1e, the goal is to have it mirrorred on
da1s1e. I've read www.vinumvm.org/vinum/fullintro.html (a bit over my
head), and am trying to go along /usr/share/doc/articles/vinum/.
> boot -s
# ^J
# cd /root
# disklabel -R da0s1 dl.da0s1
# disklabel -R da1s1 dl.da1s1
# fsck -p /
# mount -u /
# vinum create mirror.a
# fsck -p /
# mount -u /
# vinum create mirror.a

vinum mirror.p0 is up
