Package: grub-pc
Version: 1.99-22.1
Severity: important
Tags: d-i
My setup:
Wheezy businesscard install daily build (2012-06-25)
MBR on disks
One partition per disk
6 disk mdraid RAID6
/ and /boot on LVM
/ and /boot as ext4 (in fact on the same partition)
The installer installs everything fine, but grub fails to boot. Grub
can see the ext4 partitions on the lvm just fine, but with various
levels of failure cannot read the contents of them (they are either
not read at all or then they are corrupted in various ways).
After booting into recovery mode and letting the raid array build
itself the system boots up just fine after the array has finished
syncing. This is an acceptable workaround for a home system, but not
really acceptable for production environments (rebooting with a
degraded array can cause major downtime while the array syncs in a
single user mode recovery environment; alternatively someone has to
rush on-site with a newer grub boot medium to boot the system
normally).
I believe this upstream bug to be the bug in question:
https://savannah.gnu.org/bugs/?35843
Upstream claims it fixed in a newer version.
I have cross-verified this myself by having had success with Fedora 17,
Arch and Gentoo and failing with both Debian (6, 7) and Ubuntu (10.04,
12.04). The difference being that Debian and Ubuntu are on grub-pc 1.9x
while both Arch and Fedora 17 are on grub-pc 2.0+ and the Gentoo in
question is on latest (circa 2012-06-25) bzr from the GNU savannah.
A proposed solution would be to either move forward to match upstream
or to go and cherry-pick and backport the relevant change in question.
I unfortunately do not have the expertise to help you with this
process.
This bug report is being sent from an unbootable test setup in Virtualbox.
I have tagged this report relevant to the Debian installer due to the
install process leaving an unbootable system without extra steps.
