Hi !

I want to establish a mirrored (failsafe) OpenBSD with two IDE Disk.

First it is unclear if it's possible to boot from the mirrored disk. Do
I have to boot
a kernel from floppy ? Do I need an extra partition ?

Second I think I have to options to establish a mirror: ccd or raidctl
Are both failesafe ( i.e. the systems runs if one disk crashes ) ?

Cheers,
Andi

i am not very familure with raids and raid levels but i do know their is
one raid level that will just mirror a hard drive
being mirrord yes it should boot
but i dont know if you need to make changes
like swap the drives slave/master or scsi id

Read more about raidctl... it's what you want.
