My configuration is:
AMD K6-3 with 256MB memory
2x18GB IBM IDE Disks
FreeBSD 3.3-Release
My Vinum Config is:
drive d1 device /dev/wd2h
drive d2 device /dev/wd0g
volume home
plex org concat
sd length 12990M drive d1
plex org concat
sd length 12990M drive d2
vinum create -f /etc/vinum.conf yields:

At this point, I reboot then:
vinum start
Fatal trap 12
Fault Virtual Address 0x10
Fault Code Supervisor Read, Page Not Present
Instruction Pointer 0x8:0xc2109317
Stack Pointer 0x10:0xcf0a8c44
Frame Pointer 0x10:0xcf0a8c98
blah, blah, blah
This is repeatable, at least in my environment
I've also tried this after mounting the volume, after vinum init of one
or both plexes, after reintegrating a downed plex, with only one plex
defined for the volume, and using "vinum read" rather than "vinum
start"...
In other words, it works great as long as I configure it by hand...
BUT... as soon as I try to let it configure itself, down it goes,
If, instead of doing a "vinum read" or "vinum start" I use "vinum
create" again, all is well, BTW... but this is a bit messy in a
production environment.
Any Ideas?
Thanks,
Doug King
