trying to add another harddisk so i am following the guide to add extra disk at
http://wiki.contribs.org/AddExtraHardDisk but when i try to add the new disk to raid 1 i get an error saying:
mdadm: '1' is an unusual number of drives for an array, so it is probably a mistake. If you really mean it you will need to specify --force before setting the number of drivers.
this is the command i do:mdadm --create --verbose /dev/md3 --level=1 --raid-devices=1 /dev/hdc1
this command gives me something perhaps with the answer but i dont want to do anything until someone confirms it:mdadm --detail --scan --verbose
ARRAY /dev/md2 level=raid1 num-devices=2 UUID=
ARRAY /dev/md1 level=raid1 num-devices=2 UUID=
i guess i should change --raid-devices= from '1' to '2' ??
