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)?
2. Can a install grub on the replaced boot drive with the system still running?
TIA
