[Bug 878070] Re: /usr/sbin/grub-probe: error: no mapping exists for `rootvol-boot'.

[Brian J. Murrell]

Since I've just spent (read: wasted) my whole afternoon resurrecting an
unbootable LTS machine, I ask, for the second time:

Can you post here the ticket number for the lucid specific task? Why
open a new ticket anyway? This ticket was opened about Lucid
specifically. I don't think it should have been changed to Fix Released
but instead the issue of updating grub2 on Lucid could/should very well
just be tracked in this ticket.

Title:
  /usr/sbin/grub-probe: error: no mapping exists for `rootvol-boot'.

Status in “grub2” package in Ubuntu:
  Fix Released

Bug description:
  # grub-install /dev/sda
  /usr/sbin/grub-probe: error: no mapping exists for `rootvol-boot'.
  Auto-detection of a filesystem module failed.
  Please specify the module with the option `--modules' explicitly.

  Clearly rootvol-boot is an LVM LV.  It has an ext4 filesystem on it.

  Not sure what else to tell you or say.  Please let me know if there is
  any further info you need/want.
