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

[Rolf Leggewie]

I understand your frustrations, but please calm down.  Expletives don't
help anyone.  I am not a dev, I merely triage bugs.  And only by chance
did I revisit this ticket now.

I'll gladly explain how this works.  This ticket is marked fix for the
latest development release which by now is precise.  Any release with
1.99~rc1-13ubuntu3 or later will not be affected.  Unfortunately, that
does not include Lucid.  So, what will need to happen is an SRU
(https://wiki.ubuntu.com/StableReleaseUpdates).  In the most simple
terms, someone needs to come up with a minimal patch to address this and
only this problem.  Any unrelated changes in code or updating the whole
package would not be permissible.  Thus, I labeled this ticket as
"Affecting lucid" to request such a backport.  Alas, I'm not sure this
will happen in due time, but it's out of my control.  I hope you will
find this explanation of the process at least helpful.  I agree the
result is not always pretty, but it's the best the community can do.

LTS should not be confused with bug-free or the focus of development.

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.
