Hi,

I've got two 36G SCSI disks I want to mirror on a new server I'm building
with FreeBSD 4.2.  This is my first exposure to vinum, though we do have a
long installed and working vinum 3.3 machine.  The server has a 6G IDE
boot disk, 1G RAM, dual 850 Pentiums.  4.2-RELEASE GENERIC kernel running.

I read somewhere that there are significant differences in vinum as of
4.0, so I'm not sure if that explains some of the differences I see:

3.3:/dev/vinum

All I did to get vinum going so far was to set

start_vinum="YES"

in /etc/rc.conf and reboot.  Now, when I do this:

su-2.04# vinum
Can't open /dev/vinum/Control: Operation not permitted

I get that message.  /dev/MAKEDEV knows nothing about vinum either.  If
someone can help me get this going, I would be happy to write a vinum
how-to document or something...  I didn't find much about vinum under 4.x
in the mailing list archives.

Thanks in advance,

James
