Two days ago, I tried to upgrade to Maverick (server version) using
sudo do-release-upgrade
All went well, but on the first reboot after the installation the PC hangs with grub prompt:
error: the symbol grub_xputs not found
I guess it has something to do with my RAID1 setup:
sda1/sdb1 ........ RAID1, bootable (system partition, 20 GB)
sdc1 ............. swap partition
sda2/sdb2/sdc2 ... RAID5 (data partition, 3 TB)
I made a bootable (using UNetbootin) USB pen drive with 10.10 desktop on it and booted into this desktop version.
After
mdadm --assemble --scan
I could successfully access (and mount) my RAID1 and RAID5 drives.
However, the system itself does not boot.
... another thing: after only having mounted /dev/md0 and browsed in the contents, the boot behavior has changed: now the PC does not end up in the grub prompt "the symbol grub_xputs not found", but instead a blank black screen with a blinking cursor left top is shown. Keyboard: no reaction (I tried Enter, Esc, any keys ... no reaction, just a blinking cursor).
Then, I tried:
boot into USB pen drive 10.10 desktop
mdadm --assemble --scan ... result: /dev/md0 is available (the RAID1 of sda1 and sdb1)
mount /dev/md0 /mnt/md0
in /mnt/mnd0/boot/grub/grub.cfg: I replaced the kernel file names by the current ones:
2.6.32-22-server ----> 2.6.35-24-server
reboot: still only a blinking cursor
then:
boot into USB pen drive 10.10 desktop
grub-install --root-directory /mnt/md0 /dev/sda
... a message prints: no problems encountered
grub-install --root-directory /mnt/md0 /dev/sdb
... a message prints: no problems encountered
reboot: still only a blinking cursor
So at the moment I end up with a system which does not boot but gives me a blinking cursor.
Any help greatly appreciated!
Thanks,
Andi
