Mounting software RAID in rescue mode

English Install/Boot/Login
1

I have a software RAID 1 (mirroring) on my 2 hard drives configured through OpenSuse 11.3 installer. When I boot from the OpenSuse 11.3 install DVD in rescue mode, the RAID isn’t recognized, ie attempting to mount /dev/md0 results in ‘bad superblock’ messages. I can still mount individual disks in the array though (/dev/sda1, /dev/sdb1, I did it read-only so not to corrupt the array).

I also tried booting from the Centos 5.5 install DVD in rescue mode on the same computer and it has no problems finding the RAID 1. I was able to mount /dev/md0.

Is the OpenSuse 11.3 install DVD in the rescue mode not supposed to find the RAID 1 or am I doing something wrong here?

If /dev/md0 exists, I suppose the message means you have to fsck it. I’m
unsure.

What does mdadm --detail /dev/md0 show?

Mmm, I resurrected an 2 month old, dead, thread by error.
