Hi,
First: do _NOT_ use vinum on 5.4, use gvinum.

gvinum. Just to be safe you could move the vinum command and kernel modules
out of the way.

Did you start from scratch by wiping the former configuration without loadi=
ng
gvinum?
Use
# dd if=3D/dev/zero of=3D/dev/da0 bs=3D1m count=3D128
to be sure. Do this WITHOUT loading any of the vinum modules.

I don't understand this. Here is my gvinum.conf for my mirrored system
at home:
%%%
drive pain device /dev/ad4s1e
drive panic device /dev/ad6s1e
volume root
plex org concat
sd length 192m drive pain
plex org concat
sd length 192m drive panic
volume swap
plex org concat
sd length 2080m drive pain
plex org concat
sd length 2080m drive panic
volume usr
plex org concat
sd length 6g drive pain
plex org concat
sd length 6g drive panic
volume var
plex org concat
sd length 256m drive pain
plex org concat
sd length 256m drive panic
volume local
plex org concat
sd length 0 drive pain
plex org concat
sd length 0 drive panic
%%%
Be aware that gvinum's configuration syntax only allows the short forms
for many keywords.
/dev/ad4s1 and /dev/ad6s1 have this label:
%%%
[stijn@firsa] <~> sudo bsdlabel ad4s1
# /dev/ad4s1:
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
a: 393216 281 4.2BSD 0 0 0
c: 156249009 0 unused 0 0 # "raw" part, don'=
t edit
e: 156248993 16 vinum
%%%

No, vinum.autostart is for legacy vinum.

Don't do that, it's not necessary to edit anything in /etc/rc.d.

Use only vinum BSD partitions for gvinum drive declarations.

Keep at it until it makes sense, that's what I did. There are a lot of
concepts to get until it clicks.
