vinum setup

[synrat]

thanx Greg, you're right as always.
I booted into single user from start up and sure enough everything was
editable then.

I got another problem though.

I set up 2 disks for vinum and want to allocate exisiting partitions to
vinum mirrored volumes. I left 16 blocks at the begining, moved first
partition ( swap ) to 281, recalculated offsets in vinum config with -16, run vinum
config, everything's peachy, drives rebuild, fsck sees no errors, I edit
fstab, reboot, vinum module loads but root can not be mounted as a vinum
device, I still have to manually specify my regular root (
/dev/das1a ) partition. dmesg output below and vinum/disklabel too.

thanx a million. Greg for US president :)

Mounting root from ufs:/dev/vinum/root
missing unit number
setrootbyname failed
ffs_mountroot: can't find rootvp
Root mount failed: 6


disklabel ( similar for both disks )
