Yesterday I did a kernel update on a virtual machine. When I restarted the machine unfortunately I got the error Kernel panic - not syncing VFS

After some searching I found out I should go to GRUB and just select the old kernel and everything would be fine.

Wel I selected the old kernel but came to the following error; VFS: Cannot open root device "mapper/vg_cpanel-lv_root

Error trace

So after some digging I found, this question somewhere else. I went to rescue mode and do vim /boot/grub/device.map and 1 line appears (fd0) /dev/fd0 (nothing more).

I did a fdisk -l; enter image description here

But there ends the train for me, unfortunately. Following are 2 screen shots of my grub command;

All commands kernel command

I hope someone can point me in the right direction.


Well I did "solve" it. Still don't know how.

I contacted a system friend of mine which pointed me to this answer. I followed it but did not got past the second command.

I reset the system and somehow we got a third option in the GRUB which did work (magic) so now the system is running again.

So boys and girls don't forget to backup your stuff
