I've done a fresh install on a new system with 2 SATA drives, Seagate
80GB each. This is the first time I've done an installation where I
used software raid to provide mirroring capability to the system. The
raid is level 1 for mirroring. I used the installation documention on
RedHat's enterprise site to go thru the installation/configuration for
this. I didn't receive any errors during the installation, but after
the system boots grub issues the following messages:
================================================================================
grub loading stage1.5.
Error 15
================================================================================
Using the anaconda graphical installer, I've partitioned the drives as
follows:
/dev/sda
/dev/sdb
/dev/sda1 100mb /dev/md0 /boot
/dev/sda2 76215mb /dev/md1 LVM VolGroup00
/dev/sdb1 100mb /dev/md0 /boot
/dev/sdb2 76215mb /dev/md1 LVM VolGroup00
VolGroup00 76192mb
LogVol00 swap 2048mb
LogVol01 /root ext3 20480mb
LogVol02 /home ext3 20480mb
During my research into the error above, it appears as though grub
cannot find the /boot partition to continue loading the subsequent
stages. I'm hoping to find some general help from the list if possible.
A couple of questions come to mind. Can grub boot off of a raid defined
partition?
If yes, what magic incantations would be appropriate?
If no, should I just revert to a bare ext3 partition and don't
implement raid on
/boot?
Relavant parts of /boot/grub/grub.conf are:
default=0
timeout=5
splashimage=(hd0,0)/grub/spalsh.xmp.gz
hiddenmenu
