I have followed the procedure on the Centos page:
http://wiki.centos.org/HowTos/CentOS5ConvertToRAID
My setup is slightly different. I am using two partitions, / and /home. I have setup swap as a file, /home/swapfile.
My hard drives are 500Gig sda and sdb.
In modifying the instructions for initializing sdb I have:
used /dev/md0 for / (sdb1) used /dev/md1 for /home (sdb2)
In section 3.6
The line: mount /dev/RaidSys/Root /mnt/root.new
was changed to mount /dev/md0 /mnt/root.new
Everything seems to go well until I get to section 4.4.1/4.4.2 Install grub. The commands for installing grub show success but when I edit the /mnt/root.new/boot/grub/menu.lst the contents still point to hd0 not hd1.
In section 4.4.4 I am not sure how the following should be changed: umount /mnt/boot.new mount /dev/md0 /mnt/root.new/boot
The umount is not needed in my case but should the second line be: mount /dev/md0 /mnt/root.new
Other info I have found includes creating a /etc/mdadm.conf. This is not referred to in the instructions.
Are the changes I have made correct? Am I missing any other changes?
Thanks for any help,
David
