I guess you are pretty tired of me by now, but I hope there is some
patience left out there.
I have the following scenario:
Netra X1, two Seagate Barracuda-drives that both claim to be 80GB in
size. In reality, they differ by 300 megs or so in available size.
/dev/ad0 is the smaller one.
/dev/ad1 is the bigger one.
I install FreeBSD on the smaller drive, do all the gmirror stuff,
copy all contents on /dev/ad0 to /dev/mirror/gm0 (/dev/ad1 inserted
in the raid), edit fstab and loader.conf on both /dev/ad0 and /dev/
mirror/gm0 to point the root directory to /dev/mirror/gm0.
Then I reboot. And suddenly, /dev/ad1 is listed as /dev/ad0 when I do
a gmirror status.

The original /dev/ad0 is now known as /dev/ad1 and of course, now
it's too small to be added to the raid. Also, note that the size of /
dev/mirror/gm0 and /dev/ad0 in the above list differs.
The easy solution would to simply switch places of the drives, re-
install FreeBSD and then the problem would be solved, but it turns
out it isn't. I've tried that too, and result is still the same for
some reason that I don't understand.
I'm tearing out whatever hair I have left as I've spent an entire
weekend working on solving this.
Thanks for you patience.
