I have a virtualized server running 10.04 LTS that is no longer booting. We had a number of issues with our SAN that abruptly disconnected the storage from the virtual machine infrastructure and wreaked general havoc. The issue I began with was an error:

Target filesystem doesn't have /sbin/init

So I checked for the particular error and found that running boot-repair would be the best course of action. So I ran boot-repair.

When running boot repair I get an error:

/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).

and I am also presented with a grub prompt on restart (which makes sense since boot-repair doesn't seem to be writing the boot info properly). I can access (it is mounted and seems fine) the partition from a LiveCD and all the data is there so I am hopeful that this can be corrected.

The boot-repair log can be found at http://paste.ubuntu.com/5650377

A user on another post at ubuntuforums.org requested that I run:

dd if=/dev/sda5 bs=512 count=255 skip=1 of=/tmp/sda5.txt

The results of which can be found at https://gist.github.com/shanepinnell/5258498

Any and all help is greatly appreciated


Found a solution:

Once at a grub menu

  • grub> linux (hd0,1)/boot/vmlinuz-[tab to autocomplete] root=/dev/sda1
  • grub> initrd (hd0,1)/boot/initrd.img-[tab to autocomplete]
  • grub> boot

After a successful boot + sudo grub-mkconfig + sudo update-grub

Everything works now!
