I previously had a working RAID 1 array. I think as a result of running
grub-install /dev/sdb and
grub-install /dev/sdc I somehow wiped my computer of
I need to set them up again. When I try to create the
md0 array, I am getting the following error.
/dev# mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sda1 missing -f mdadm: device /dev/sda1 not suitable for any style of array
It seems like Debian thinks the drive is already in an array but it's not.
