[Bug 563895] Re: grub2 fails to boot or install when an LVM snapshot exists

[dblade]

Most people applied the fixed package manually and moved on over a year
ago.  Are you really surprised?

I'm not here to debate whether or not is right or wrong to report a bug,
or provide info regarding a bug, and then not be involved every step of
the way.   People have the right to contribute or not contribute as they
see fit.  Your attitude is not going to affect this fact in a positive
way.

All you have really achieved here is made pull my name off the CC list
for this bug.  I did it because the latest updates you've made are the
equivalent of spam.

Maybe you need to take a step back and realize how little control you
actually have on this matter.

Title:
  grub2 fails to boot or install when an LVM snapshot exists

Status in “grub2” package in Ubuntu:
  Fix Released
Status in “grub2” source package in Lucid:
  Fix Committed
Status in “grub2” package in Debian:
  Fix Released

Bug description:
  SRU Justification:

  Impact: When /boot and / are in an LVM VG and a snapshot is made of an
  LVM LV in that VG the system will not boot and grub can not be
  modified (updated, reinstalled) until all snapshots are removed.

  Testcase:

  Binary package hint: grub2

  Steps to reproduce:

  - (Lucid beta2 installed from CD)
  - Take a snapshot of any volume
  - on reboot:
    error: fd0 read error.
    error: no such disk.
    grub rescue>
  - Use the rescue cd to get a root shell
  - Remove the snapshot and reboot
  Now, the system boots. Create a new snapshot to repeat.

  The system has 2 SATA disks in mdadm RAID1 configuration with 1 lvm
  volume on top and no 'normal' partitions.
