Try the params on the /boot/grub/menu.lst line
OK - So I am starting from scratch again since my previous attempt failed. I boot from the disk. Load modprobe raid1 modules from command line and then create the RAID1 mirror with 'mdadm'. I have recreated the partitions:
sda1 = 4 GB /boot (bootable) sda2 = the rest of the disk (RAID)
sdb1 = 4 GB SWAP (SWAP) sdb2 = the rest of the disk (RAID)
Below I created the same RAID.
#mdadm --create /dev/md0 --level=2 --raid-devices=2 /dev/sda2 /dev/sdb2
**I allowed the mirror to synchronize over night. Right now as I type this, the mirror is done syncing.
So according to everything we previously discussed, I don't need to mess with anything else and can go into the /arch/setup and configure my system, right? I should simply only make changes to my menu.lst as
Yes
noted above, and nothing else when I am prompted to 'Configure System'?
Just add raid to the HOOKS line in to generate th initrd (and whatever else you need there for your system) in mkinitrd configure. I don't put the madam in the HOOKS line, it always fails for me.
So am changing the 'kernel' line in the Grub 'menu.lst' to read as follows:
kernel vmlinuz26 root=/dev/md0 md=2,/dev/sda2,/dev/sdb2 ro
Good, what that says is the root filesystem is on /dev/md0, and the array is made up of two drives, list of the drives. Now grub knows how to handle the array.
*Note the 'ro' at the end. It was already there before I add your suggestion in the middle. Do I take it off or leave it on?*
The ro is fine on the above line.
Please let me know if I have missed anything.
I don't think so. Your above setup is how I do the raid
