Then reinstall grub on the drive.
Now I have some questions:
1. Since the /boot partition was mirrored and will be restored on the
new sda drive I do not really want to do a full grub install. From
what I have read that will overwrite existing /boot/grub/grub.conf
file. So I just want to write the MBR on the drive. How to I do
that (the docs I have found were rather unclear on that aspect)?
2. Can a install grub on the replaced boot drive with the system still
running?
Yes, after the /boot partition re-sync has completed, execute grub and:
root (hd0,0)
setup (hd0)
quit
If you aren't able to keep the system running while doing the swap, you
can also do this from the rescue mode boot, but you should have the
contents on the /boot partition first.
Sorry to be obtuse here but I just want to make very sure of what I am
doing before I do it. Will the "setup" command only write the MBR?
Yes, it will verify that the root partition (grub calls /boot root since
that's all it knows about) looks right, then write the MBR.
