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 title CentOS-4 i386 (2.6.9-22.EL) root (hd0,0) kernel /vmlinuz-2.6.9-22.EL ro root=/dev/VolGroup00/LogVol01 initrd /initrd-2.6.9-22.EL.img
And this is CentOS 4.2.
