I am replacing 2 machines
1 - OpenBSD (single drive)
Webserver, SMTP Gateway, Dhcp Server
1 - linux (currently has a hardware RAID) card
Email server for 10 users
with
1 - OpenBSD box, with 2 disks to do the same task.
I know that OpenBSD does not support "Root on Raid" as of yet.
My question
What is the best way to "mirror" the primary disk so that in case of
disk failure I can just move the second disk to the primary and then
use it ?
This would be a manual process , not looking for any automatic fail over

I have considered just loading the OS on each disk then putting the second on
as a slave disk and then just rsyncing the changes over to it..

Thoughts.. ???
