Here's my current info on how to build a root mirror with software RAID. http://scsirastools.sourceforge.net/docs/UserGuide (section 4.0) I used the HOWTO, with some things added that I learned along the way. The 15 steps are scripted, and the scripts are broken out in the CVS tree as files/md*.sh The instructions are oriented to lilo, but the grub equivalent is scripted in files/mdevt script: http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/scsirastools/s csirastools/files/mdevt?rev=HEAD&content-type=text/plain Andy -----Original Message----- From: Eric Wood [mailto:eric@interplas.com] Sent: Tuesday, September 09, 2003 2:18 PM To: linux-raid@vger.kernel.org Subject: Converting a non-RAID RedHat System to run on Software RAID I frequently want to convert an existing single drive install of RH linux into a mirrored RAID-1 set. 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 - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
