Package: grub-pc
Version: 1.97+experimental.20091213-1
Severity: important
I get the following warning and error when I attempt to install or update grub:
/usr/sbin/grub-setup: warn: Your core.img is unusually large. It won't fit in
the embedding area.
/usr/sbin/grub-setup: error: Embedding is not possible, but this is required
when the root device is on a RAID array or LVM volume.
my / (root,boot) partition is a lvm volume, as is my swap. When I first
installed the OS (debian sid) a month and a half ago, everything including
grub-pc installed. And the machine would boot, albeit with grub taking several
seconds to actually show the boot menu (it would briefly flash to the grub
rescue cli).
sdf and sdg both have a single dos/pc style partition which are combined into
a md-raid1 volume, which is "exported" as a LVM2 volume group, which is where
/, /home, and swap live (as well as several KVM vm volumes).
I hessitate to reboot this machine as it hosts my firewall, a couple public
websites, and asterisk to handle my home phone. If grub failed, it would take
all my services down, including my internet for an unknown length of time.
The rest of the disks are unrelated, and make up a 5x1TB raid5 volume.
I asked about this on #g...@irc.freenode.net and one person said it might
be related to compiler options used, which bloat the size of the grub driver
modules.
