Re: Re: [Grml] [Grml 1.0] cannot boot anymore after upgrade
Hi Mika,
first of all, thank you very much for the fast reply. I guess you know how frustrating it can be to spend many hours on a problem and finally ending up with no idea how to go on. So I was very glad to find your reply in my inbox so soon :-)
The last 1-2 lines of the output would be interesting.
Here are the error messages when booting with LILO: ---- [....] No root-on-loop configured, skipping Begin: Loading MD modules ... Failure: failed to load module linear.

Can you please provide the output of: dpkg --list mdadm lvm2 initramfs-tools lilo grub udev of the system? (Just boot grml live and chroot into your system)

I already did that in the case of grub (see modified menu.lst above). The result is the same. Or did I miss a step somewhere? After changing the menu.lst do I have to do any additional steps? (I think I reinstalled grub after that, but I am not sure.)
By the way: I got the GRML virtual appliance from: http://www.vmware.com/appliances/directory/899 (I don't know whether the distributor modified the VMachine in the meantime.)
Thanks again for your help. Hope you can guide me how to resolve that problem.
Best regards,

Thanks, definitely helps debugging the problem.
Can you please provide the output of: dpkg --list mdadm lvm2 initramfs-tools lilo grub udev of the system? (Just boot grml live and chroot into your system)

You are sure, that this is the output of the affected grml2hd installation? This would be interesting. :)
Here is lilo.conf (which I currently use):
lba32 prompt timeout=50 map=/boot/map vga=normal boot=/dev/sda image=/boot/vmlinuz-2.6.20-grml label="2.6.20-grml append="grml_from_hd root=UUID=ffb575cc-c8df-4063-e0f8cb6aff03 " read-only vga=0x0317 initrd=/boot/initrd.img-2.6.20-grml
=> I left out only the other sections and the bootscreen related lines => I tried also without boot screen => I checked that all the files mentioned above do really exist => the UUID is the correct one (checked with Ubuntu live CD) => the hard disk is really sda (the only existing partition is sda1)
Ok, so just replace the:
append="grml_from_hd root=UUID=ffb575cc-c8df-4063-e0f8cb6aff03 "
with
append="grml_from_hd root=/dev/sda1"
Here is the current menu.lst (after removal of comments etc):
-> this one is the one with /dev/sdX:

=> as I said: I also found detailed descriptions how to install grub manually which I followed exactly (http://www.gnu.org/software/grub/manual/grub.html#Installing-GRUB-natively) => the result was the same (only 'GRUB' being displayed before the system was hanging)

You can edit the commandline of grub interactive (just press 'e', then edit the according line(s) and after pressing 'enter' to activate the changes, finally boot the entry using 'b') as well.
You can check your configuration booting with an additional 'rootdelay=1' bootoption (you can add that interactive in grub as well as in lilo!). Then (when failing to boot and getting dropped into the initramfs shell) just check output of 'cat /proc/cmdline'.
If it works with root=/dev/... and fails with root=UUID=... we are talking about the problem I could reproduce and are debugging right now.

Ah cool, thanks for the pointer - I wasn't aware of that. :)
