I used a grml x86-64 boot cd and it seemed to create hda as sdc. I mounted sdc1 and md0 to /mnt and used: rsync -cavHh --progress --delete /mnt/sdc1 /mnt/md0 After rebooting back to hda1 I changed fstab to put root on /dev/md0 and changed menu.lst on /mnt/md0. Rebooted and moved the ide to the bottom of the boot list in cmos so the 2 sata drives are listed first. It seems to have booted to md0 ok. Now I need to confirm everything is set correct. Before when at the grub boot menu when booting with the ide moved below the sata drives, droping to command line for grub showed that the ide drive only moved down 1, not 2. It seemed to have: hd0 = sda hd1 = hda hd2 = sdb Now with the array booted, going to the grub command line and using auto complete for "root (hd0," it seems to be using the device map at this point which is no longer correct: (hd0) /dev/hda (hd1) /dev/sda (hd2) /dev/sdb Note that in the other system, because linux was installed with only the ide and 1 sata drive, it doesn't even list the other two in it's device map. So what is the best/safest way to update/correct this to what ever it should be? ============================================= Moving swap: I have used "sudo mkswap /dev/md1" so if I read info correct, I should be able to just change fstab: /dev/md1 none swap sw 0 0 and reboot to start using md1 array for swap? ============================================= menu.lst updates: The guides all call for assorted changes to menu.lst Some of the guides call for adding the line savedefault to kernel entries but the people in #grub said not to do that with a raid system as it would corrupt the array and I thought I saw something about that reading about grub but can't find it. Some guides call for adding "fallback 1" after "default 0". And all call for adding duplicating the first kernel entry but changing root to (1,0) for the second entry. But some have said it's not needed. Sorry of some of these questions have been answered before, But I want to make sure everything is updated/corrected as needed before moving on to the other stuff I need to do. Don't want to get nearly done and have a nasty suprise down the road or the next time I build/install a new kernel because something was missed. menu.lst as it is now: # menu.lst - See: grub(8), info grub, update-grub(8) # grub-install(8), grub-floppy(8), # grub-md5-crypt, /usr/share/doc/grub # and /usr/share/doc/grub-legacy-doc/. ## default num # Set the default entry to the entry number NUM.
