Hello Chris,
Before setting up your mirror, I recommanded you to read "RAID options
for OpenBSD" from the OpenBSD FAQ
(http://www.openbsd.org/faq/faq14.html#RAID) and then the following
manuals (which I did when I teached myself making a RAIDFRAME mirror on
4.2) :
* raid(4),
* raidctl(8),
* newfs(8),
* disklabel(8),
* fdisk(8),
* boot(8),
* installboot(8),
* dd(1),
With the same steps, my configuration is working on 4.3 & 4.4 (amd64).
You can also *precisely* describe your steps (commands and traces), and
in this case, I could easely help you.
Best regards,
Chris Harries a icrit :
