The first thing you need to really, really understand is that the software RAID is done by *partition*, not by drive. Therefore, you're not mirroring /dev/hda and /dev/hdb - you may be mirroring /dev/hda1 with /dev/hdb1, etc. You are probably not mirroring your swap partition. > /dev/had has failed and I need to replace > it.

If you've mirrored *everything*, then you can drop the drive out, replace it, and then run grub-install to put the boot block back. If you forget and then try to reboot, you can boot into rescue mode and run grub-install from there. > Should I swap had and hdb so the good drive is first and replace the > second drive? Has anyone done this before? I believe this is documented in the software raid HOWTOs and there is a link in the Red Hat online documentation on what you need to do. I haven't read it lately though and I don't currently mirror my boot disks. -- Ed Wilts, RHCE Mounds View, MN, USA mailto:ewilts@xxxxxxxxxx Member #1, Red Hat Community Ambassador Program -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
