mdadm.conf on mkinitrd does not include my raid1 /boot partition

English Install/Boot/Login
#1

After kernel update the system does not boot… well It boots as rescue login.
I have a raid10 / (ext4) and a raid1 /boot (ext3) on OpenSuse 12.2 X86_64.
When booting it mounts /, then it waits a while and shows rescue login.

I guessed it was a problem with raid during boot so I commented /boot line in /etc/fstab and then it boots fine
Once It has booted I can mount /boot.

My mdadm.conf is


root@tutatis:/home/fperal> cat /etc/mdadm.conf

But mdadm.conf on initrd does not include md0

But it does not change mdadm.conf in initrd.
I can manually edit initrd and change it but I think I will have the same problem again next time, so How can I make mkinitrd to use /etc/mdadm.conf

#2

Generally failure to boot after kernel change is caused by video drivers installed the hard way. If you did then you need to reinstall the driver.

#3

Why should it? initrd includes what is required to mount root file system and /boot is not needed for it. You need to find out the root cause why md0 is not found during boot and fix it; adding it to initrd is just a workaround. One possible reason is home host mismatch.

#4

OK. You’re right.
The problem wasn’t /boot partition, was that I have included some lines on /etc/fstab to let normal users mount some flash drives (I don’t know why but trying to mount them from kde device notifier fails) and I forgot using the noauto option, so the system was trying to mount them all and obviously they weren’t there.
When I looked at /etc/fstab and I comented the /boot line I comented theese too, but I was thinking on the mdadm.conf issue so I didn’t realize that there may be another problem.
