What are some better ways to turn on RAID level 0 in OpenBSD 4.2 -
stable - and still stay with the GENERIC kernel?
My first try worked but I went about it by making a new kernel, which is
frowned upon and probably adds unneeded steps. However, here's the change :
# diff GENERIC GENERIC.RAID
729c729
< #pseudo-device raid 4 # RAIDframe disk driver
---
> pseudo-device raid 4 # RAIDframe disk driver
To put it into context here are the steps to make the RAID device:
# prepare first drive unit
fdisk -i wd1
disklabel -E wd1
newfs -q wd1a
# prepare second drive unit
fdisk -i wd2
disklabel -E wd2
newfs -q wd2a
# raid specifications
cat << CONF > /etc/raid0.conf
START array
1 2 0
START disks
/dev/wd1a
/dev/wd2a
START layout
128 1 1 1
START queue
fifo 100
CONF
# first-time configuration
raidctl -C /etc/raid0.conf raid0
# check is it there
raidctl -s raid0
# create disklable and file system on raid device
disklabel -E raid0
newfs -q raid0a
# set mount options
cat << FSTAB > /etc/fstab
/dev/raid0a /raid ffs rw,nodev,nosuid 1 2
FSTAB
# create mount point
mkdir /raid && mount
# check and re-initialize the parity
raidctl -vP raid0
# rebuild
raidctl -R /dev/wd1a raid0
