Hello,
I upgraded my system from Red Hat FC10 to FC11. The instructions
say to run this command:
/sbin/grub-install BOOTDEVICE
And if it fails, run this:
/sbin/grub-install --recheck /dev/sda
However, my boot disk (/boot) is mirrored on 4 disks and I think (or hope)
all 4 are bootable. The mirrors were created at install time many years ago
when I installed FC5. No idea if it really made more than 1 bootable. I
have assumed that if sda failed, I could still boot from sdb, sdc or sdd.
And I do understand that I might need to remove sda first, depending on the
type of failure. Lucky for me, no drive has failed yet and I don't recall
if I tested booting off of any other disks.
I do have this on the kernel line:
md-mod.start_dirty_degraded=1
So, what do I do now? Run that command on all 4 disks? Or run it on
/dev/md0?
Oh, 4 way mirror is not because I am paranoid. I have 4 disks partitioned
alike, so I figured I would use all 4 disks just for the symmetry. OCD
maybe, but not paranoid. :)
