Is that code available somewhere or could you send it to me?
I can send it to you, but it's in a bit of a mess, since it's been
lying there for nearly three years. I could explain to you what to
do, but it would take me about as long as really doing it.
I've already got my root partition accessible both directly (so the
loader can get at it) and as a vinum mirrored volume.
I'd be interested in seeing *your* code.
Let me say in advance that it is lacking any form of error checking. I should
also find some way to determine which disk we're booting from, since that is
the only disk that makes sence to read the config from.
{
char *bootdev[]={/dev/da0,/dev/da1,NULL};
start_config(0);
lock_config();
vinum_scandisk(bootdev,sizeof(bootdev)/sizeof(bootdev[0]));
unlock_config();
finish_config(0);
save_config();
}
I've added this bit to the end of vinumattach() which seems to be working.
However the routines in kern/vfs_conf.c are unable to mount a vinum volume. Haven't
had time to really look into that.

Ah. Yes, that's partially the correct approach, but it requires you
to know *all* Vinum drives; otherwise Vinum will mark the missing ones
down. Jörg Wunsch already has functional code which does things this
way. I'm in the process of rewriting vinum_scandisk to find the
drives itself.
