So I thought I found the holy grail: http://unthought.net/Software-RAID.HOWTO/Software-RAID.HOWTO-4.html#ss4.14 However, it is slightly out dated (RH 7.1 days). Since I'm trying to mirror RH 9, I have several questions based on this HOWTO: 1. Sect. 4.14.6: /dev/md0 already existed while in rescue mode. Ignored it, no problem 2. Sect. 4.14.7: I could not umount /mnt/sysimage to save my life. Looking at what was mounted, I seen that I needed to also umount /mnt/sysimage/dev/pts. I cd'd into the / directory to make sure I wasn't holding the unmount up. So I could not proceed with the howto. 3. Sect. 4.14.11,12 should be updated to include grub. 4. Sect. 4.14.14. Do I first have to convert from ext3 back to ext2? Since I use ext3 does this step still apply or does mkraid at the second superblock in an acceptable manor for ext3? Do I still have to resize2fs the md devices? Any info I gather, I will relay to the howto author and hopefully he'll come out with an update. thanks, -eric wood
