Bug#615152: grub2: Cannot recognize FS format any more under kfreebsd ports

[Dererk]

Package: grub2
Version: 1.99~rc1-3
Severity: important
Usertags: kfreebsd


Hi there.

I've been using grub2 on my kfreebsd machines for some time now with no
issues at all, but since two or three weeks I started getting this very
exact error on both i386 and amd64 machines, one performing grub package
upgrades. Unfortunately one of them went down unexpectedly and caused me
to loose the capability to boot since I get grub entering rescue mode
without being able to perform any task other than getting "error:
unknown filesystem."

I'm using regular UFS on the root partition which holds the /boot too,
_no zfs_ on any of them.


This is the log I get from the other running machine which stills live:

root <at> ananke[~]# dpkg-reconfigure -plow grub-pc

Configuring grub-pc
-------------------

The grub-pc package is being upgraded. This menu allows you to select
which devices you'd like grub-install to be automatically run for, if any.

Running grub-install automatically is recommended in most situations, to
prevent the installed GRUB core image from getting out of sync with GRUB
modules or grub.cfg.

If you're unsure which drive is designated as boot drive by your BIOS,
it is often a good idea to install GRUB to all of them.

Note: it is possible to install GRUB to partition boot records as well,
and some appropriate partitions are offered here. However, this forces
GRUB to use the blocklist mechanism, which makes
it less reliable, and therefore is not recommended.

  1. /dev/ad0 (??? MB; ???)  2. /dev/ad0s1a (??? MB; ???)  3. none of
the above

(Enter the items you want to select, separated by spaces.)

Do you want to continue anyway? If you do, your computer may not start
up properly.

Please do let me know about any possible information I can provide you
with to solve this issue, which is quite important as it's highly likely
to render many systems unbootable.


Thanks in advance.


Cheers,

Dererk
