Greetings,
I have come across an error during preparing the rebooting of my system
with an updated kernel. I am receiving a segmentation fault during the
setup phase of grub. I have RAID 1, so grub-install does not work, of
course. I have instead either done it by hand or used my own script
(see below). I have been able to perform this task sucessfully in the
past up to this point with prior kernels on this hardware. Below is the
output when doing it manually, with /boot on /dev/hda1 mirrored to
/dev/hdb1 on an ext3 volume (/dev/md0). My lvm volume is at /dev/hda2
mirrored to /dev/hdb2 (/dev/md1). Both volumes are clean, and /dev/hdc1
and /dev/hdc2 function as hotspares for their respective partitions.
I have noted the thread "grub segmentation fault when trying to do
setup" on July 19th with an issue like this one. I was hoping that
someone would have some insight into this before I go clear across town
to boot into rescue mode to complete this task.
