Hi misc!
First of all i'm a newbie, so please excuse my lack of knowledge.
Now, let's get to the point. I'm trying to setup a raid 1 degraded
array using RAIDFRAME. I'm using a PII machine with hard-drives wd0,wd1.
Step 1)
a) recompiled the kernel with
pseudo-device raid 4
option RAID_AUTOCONFIG
b) recompiled userland.
c) made a release.
4) made a bootable iso image from the release files and burned
that image on a CDROM.
Step 2)
a) install base system with the new boot cd on wd0.
b) fdisk -i wd1; disklabel -E wd1. After labeling, wd1 looks like
this:
# /dev/rwd1c:
type: ESDI
disk: ESDI/IDE disk
label: FUJITSU MPB3032A
flags:
bytes/sector: 512
sectors/track: 63
tracks/cylinder: 16
sectors/cylinder: 1008
cylinders: 4092
total sectors: 4124736
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0 # microseconds
track-to-track seek: 0 # microseconds
drivedata: 0
16 partitions:
# size offset fstype [fsize bsize cpg]
a: 131985 63 4.2BSD 2048 16384 1
b: 263088 132048 swap
c: 4124736 0 unused 0 0
d: 3729600 395136 RAID
I've created a new filesystem on wd1a and made it bootable.
I've edited /etc/raid0.conf
START array
# numRow numCol numSpare
1 2 0
START disks
/dev/wd0d
/dev/wd1d
START layout
128 1 1 1
START queue
fifo 100
Create raid0:
raidctl -C /etc/raid0.conf raid0
Initialize component labels:
raidctl -I 100 raid0
Initialize the raid device:
raidctl -vi raid0
Check the array was created:
raidctl -vs raid0
Allow the system to use raid0 as root device:
raidctl -A root raid0
I've labeled raid0. It looks like this
# /dev/rraid0c:
type: RAID
disk: raid
label: fictitious
flags:
bytes/sector: 512
sectors/track: 128
tracks/cylinder: 8
sectors/cylinder: 1024
cylinders: 3642
total sectors: 3729536
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0 # microseconds
track-to-track seek: 0 # microseconds
drivedata: 0
16 partitions:
# size offset fstype [fsize bsize cpg]
a: 3729536 0 4.2BSD 2048 16384 1
c: 3729536 0 unused 0 0
I've mounted /dev/raid0a, copied the instalation and modified
/etc/fstab to mount /dev/raid0a as /.
I've rebooted the system. Everything works.
From dmesg:
Kernelized RAIDframe activated
raid0 at root: (RAID Level 1) total number of sectors is 3729536
(1821 MB) as root
Step 3) Mirror everything to wd0.
I've label wd0 so it looks like this.
# /dev/rwd0c:
type: ESDI
disk: ESDI/IDE disk
label: FUJITSU MPC3064A
flags:
bytes/sector: 512
sectors/track: 63
tracks/cylinder: 15
sectors/cylinder: 945
cylinders: 13410
total sectors: 12672450
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0 # microseconds
track-to-track seek: 0 # microseconds
drivedata: 0
16 partitions:
# size offset fstype [fsize bsize cpg]
a: 131292 63 4.2BSD 2048 16384 1
b: 262710 131355 swap
c: 12672450 0 unused 0 0
d: 3729600 394065 RAID
raidctl -a /dev/wd0d raid0 - add raid partition as spare
raidctl -vF component0 raid0 - force backup to spare
raidctl -vP raid0 - recreate parity
Output of raidctl -vs raid0 follows:
Components:
component0: spared
/dev/wd1d: optimal
Spares:
/dev/wd0d: used_spare
After that i've made the first disk bootable again.
Step 4) Reboot
After reboot.
The output of raidctl -vs raid0 follows:
raid0 Components:
component0: failed
/dev/wd1d: optimal
No spares.
After searching the list and google, I used /dev/wd0d as spare again and
after that tried to reinitialize components labels ( raidctl -I 200
raid0 ) or/and reinitialize the raid device ( raidctl -vi raid0 ), tried
the setup from scratch, but the outcome was still the same: component0:
failed.
|Any pointers or ideas to the problem would be highly apreciated. I've
added the dmesg from the machine to the end of this mail.
P.S.: I've followed the setup described in
