Raid 1

Ok, since i had a hard disk failure in a production box a monday evening, (a production box for sure) I now trying to setup (software) raid 1 as far it's possible. Check my jumpstart raid 1 profile. That's why - after setting up a box with raid 1 - I'm trying to remove a disk (while the OS running), I didn't have errors.

Just remember to do : 

metareplace -e d0 c1t0d0s0

for each mirror you have.

Soft partition with raid 1

Create a raid 1 mirror, and use its device for soft partitions

Create the mirror 

metainit d6 1 1 c1t0d0s5
metainit d7 1 1 c1t1d0s5
metainit d8 -m d6
metattach d8 d7

Create a soft partition 

metainit d10 -p d8 512M
