openSUSE 13.1 not booting after update (GRUB2 and RAID1) with "Waiting for device..."

fakemoth · April 24, 2014, 10:38am

Yet Another Grub Problem! Didn’t run in this kind of issue for years, but I did try anything I could fin here on the forums. Unfortunately my IP (not really mine, I guess it was a whole block) was banned, so it was a nightmare accessing threads through Googles cache… Thanks dudes!

How did this happen? 2 days ago I did an update, it involved something-something-udev-kernel firmware-etc. I regret I didn’t write this down. After the restart I was getting a freeze during boot with the message:

Waiting for device /dev/root to appear: …Could not find /dev/root.
Want me to fall back to /dev/something (Y/n) the usual story, you can’t press y or n, no terminal, nothing after the list that grub2 was displaying. But at least I got that one…

Hah, that’s easy I said! So i tried:
-booting in safe mode and with the other kernel;
-modifying the parameters, checked my uid;
-booting from the rescue CD;
-booting with the install DVD into rescue mode;
-booting with Supergrub and Rescatux - at this point it was becoming weird, giving the same error?
-messing with fstab;
-followed this mainly and everything else https://forums.opensuse.org/showthread.php/478290-Article-Re-install-Grub2-from-DVD-Rescue?p=2608924#post2608924 just adapting to my /dev/md0 (at that time); so I tried reinstalling grub2, refresh the config, by the book;
-everything seems to have no effect at all! I did manage though to change to grub 1 (with errors) via YAST in terminal chrooted into my environment with the help of the rescue cd.

Now I get a blinking grub cursor, that it doesn’t respond to any commands, I will post my details in a moment, have to boot the station in question here. I really have to make this work without a fresh install as it will take me weeks to set it up the way I need it. But also I am running out of time, because I got work to do and wasted 2 days trying things without being able to post here… So if someone could help my scenario step-by-step I would really appreciate it.

Later Edit: now from the machine in question, running Rescue CD (the one with XFCE) both the install and the CD being x86_64

Pfff can’t edit my post, you should really get rid of this… “protection”. Honest mistake, messed up the code tag. Can someone edit that?

My fstab:

 /dev/disk/by-id/ata-WDC_WD3000GLFS-01F8U0_WD-WXL408721880-part2 swap                 swap       defaults              0 0/dev/disk/by-id/ata-WDC_WD3000HLFS-01G6U4_WD-WXD0C7967189-part2 swap                 swap       defaults              0 0

/dev/md/md127          /home/fakemoth/Structure/ ext4       acl,user_xattr        1 2

As you can see I have two raid1 sets comprised of 2 HDDs each, the 300GB Velociraptor ones and the 1,5TB Seagate ones. On the md0 I have the / partition (and the swap).

And the result is… got back the nice opensuse GRUB2 but keeps on giving me the same message and it never boots:

Waiting for device /dev/root to appear: …Could not find /dev/root.
Want me to fall back to /dev/md0 (Y/n)

What is wrong here? My guess is that it’s something else… I read that maybe if one would reinstall the kernel, most problems should be gone. Using yast/zypper how can I reinstall the kernel safely from the rescue cd? Is it as simple as:


zypper remove kernel*
zypper install kernel

?

Additional info:
Tried also to mess the order in BIOS - no avail (on the other 300GB HDD sdb left the grub 1 stuff, so it starts accordingly, but it gives me the prompt)

Please show /etc/mdadm.conf and mdadm version (rpm -q mdadm). If doing it when booting from live media, you can use “rpm --root=…” or simply chroot.

I am sorry this has taken way too long for me, now I am in the process of moving data and reinstalling from scratch. I would have posted it for the record, but I tried a last desperate thing, installing again with the update option, which left me in the same spot really, not overwriting anything grub2 related. So the file is in fact another one.
