Hi,
I have been trying to configure software RAID using resources at
http://www.openbsd.org/faq/faq14.html#RAID
and
http://www.openbsd.org/faq/faq14.html#RAID
I did get the error
# raidctl -C /root/raid0.conf raid0
raidctl: ioctl (RAIDFRAME_CONFIGURE) failed
The raid configuration file entries are
=======================================================
# cat /root/raid0.conf
START array
# numRow numCol numSpare
1 2 0
START disks
/dev/wd2b # the fake device
/dev/wd1b
START layout
128 1 1 1
START queue
fifo 100
================================================
Could some one help me trouble shoot this please?
I did recompile the kernel with the following options and am booting that kernel
=================================================
# cat /usr/src/sys/arch/amd64/conf/GENERIC.RAID
include "arch/amd64/conf/GENERIC" # include GENERIC configuration
option RAID_AUTOCONFIG # automatically configure RAIDframe arrays on boot
pseudo-device raid 4 # RAIDframe disk driver
# uname -a
OpenBSD xxx.yyy.local 4.0 GENERIC.RAID#0 amd64
#
==========================================================
# disklabel -E wd1
# Inside MBR partition 3: type A6 start 63 size 234436482
Treating sectors 63-234436545 as the OpenBSD portion of the disk.
You can use the 'b' command to change this.
