OK, you just have to replace the drive, fdisk matching partitions on it
("fdisk -l /dev/sde" will show the sizes you need), then use
mdadm --add /dev/md? /dev/sda?
for each one to add the missing partition back.
I have been able to review all this and it looks very straight forward.
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)?
Boot the system from CD or similar in Rescue Mode and then use something
like
grub-install --no-floppy /dev/hda
2. Can a install grub on the replaced boot drive with the system still
running?
TIA
Regards, Hugh
Yes
