Posted: Wed Dec 08, 2004 3:30 am Post subject: Software RAID not working |
|
|
I"m trying to follow this HOW-TO about setting up Gentoo with software RAID. It's probably a simple problem, but I just can't seem to figure it out.
I'm installing from the Gentoo 2004.3-r1 minimal release. The hardware is a BE-6 mobo, PIII 550 Mhz, and both drives are on seperate channels. After I started the system, since all the networking stuff worked from boot the next thing seems to be "Set up partitions". I did the following command , fdisked both drives the same, the partition ID's are fd (except for the SWAP partition) and created my /etc/raidtab file. Now when I try to do step, I'm getting the following error message Code: | cannot determine md version: no MD device file in /dev |
I'm not sure what I'm not doing. Any help would be appreicated.
Also another question about using RAID, do I need to set my /boot partition with the boot flag? It's not mentioned in the HOW-TO so I'm guessing not, but want to be sure.
THanks,
LK |

Since the BE-6 chipset had only IDE-33, they added at HighPoint controller that added two IDE-66 connectors. So my setup is as follows:
Code: |
IDE-33 Connectors
IDE1 - CD-RW
IDE2 - Empty
IDE3 - CD-ROM
IDE4 - Empty
IDE-66 Connectors
IDE5 - WD 80 Gig (hde)
IDE6 - empty
IDE7 - WD 80 Gig (hdg)
IDE8 - empty
|
Both HD are partitioned as follows:
Code: |
Partition | Size | Type
---------------------------------
hde1 /boot | 100M | fd - RAID Autodetect
SWAP | 512M | linux swap
hde3 /home | 50 G | fd - RAID Autodetect
hde5 /var | 10 G | fd - RAID Autodetect
hde6 / | 14 G | fd - RAID Autodetect
Partition | Size | Type
---------------------------------
hdg1 /boot | 100M | fd - RAID Autodetect
SWAP | 512M | linux swap
hdg3 /home | 50 G | fd - RAID Autodetect
hdg5 /var | 10 G | fd - RAID Autodetect
hdg6 / | 14 G | fd - RAID Autodetect
|
My raidtab file is as follows:
Code: |
# /boot (RAID 1)
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
chunk-size 32
persistent-superblock 1
device /dev/hde1
raid-disk 0
device /dev/hdg1
raid-disk 1
# /home (RAID 1)
raiddev /dev/md1
raid-level 1
nr-raid-disks 2
chunk-size 32
persistent-superblock 1
device /dev/hde3
raid-disk 0
device /dev/hdg3
raid-disk 1
# /var (RAID 1)
raiddev /dev/md2
raid-level 1
nr-raid-disks 2
chunk-size 32
persistent-superblock 1
device /dev/hde5
raid-disk 0
device /dev/hdg5
raid-disk 1
# / (RAID 1)
raiddev /dev/md3
raid-level 1
nr-raid-disks 2
chunk-size 32
persistent-superblock 1
device /dev/hde6
raid-disk 0
device /dev/hdg6
raid-disk 1

Looks like modprobe md is broken, it does not create any /dev/md* devices
Well I'm fresh out og Ideas looks like all 2004.3 LiveCD's are brooken in different plases. I have tried for one week now on installing Gentoo on my new AMD64 PC.
I have tried AMD64 version of LiveCD from Stage 1 to Stage 3 none worked. I then tried the X86 LiveCD (2004.3-r1) and diden't manage to start raid
I guess I have to go for Fedora
2004.2 dosent support my raid card or network card.
I also tried AMD64 LiveCD 2004.3-r1 and nothing worked there, no fb, no keymap, no links2.... nothing ??????
I guess I'l have try again when LiveCD 2005.0 releases, and hopefully the AMD64 version is bugg free. |

Does everyone agree that it's just broken. Should I try to install from 2004.2 or maybe ealier?

Well, I tried installing from my old 2004.1 CD I had burned in preperation to install Gentoo back when 2004.1 came out, but didn't get around to it. Well after I did "modprobe md" I checked '/dev' for md devices and sure enough they where there. The rest of the install when smootly until I had to 'emerge --sync' which then couldn't connect. I had to got to bed so I'll try again today when I get home from work.
So does this mean that 2004.3 is broken?
Another question I have would be, can I install from the 2004.1 CD and still use the 2004.3 Stage1 to install the base system? I would think it would work, but are there known issues with doing this?
Thanks,
