Sorry if this is the wrong list to post this on.
It's the right list.
I have made an error when creating a new raid1 array as I specified that
the raid should consist of only one disk. Now, I would like to add another disk, but mdadm insists on adding it as a spare disk, offering no data redundancy.
I have read the manpages, and tried googling without success.
I do not wish to destroy the data on the discs, and recreate the array but It might be a last resort. Can anyone help me convince mdadm to add the 2. partition as an active disk.
You could keep your data by doing this:
Remove the current spare:
mdadm --remove /dev/md/0 /dev/ide/host0/bus0/target0/lun0/part1[0]
Create new array with
mdadm --create /dev/md/1 --level=1 --raid-devices=/dev/ide/host0/bus0/target0/lun0/part1[0] missing
Then create fs on new array, mount & copy data to the new array. Stop the old array, add disk from old array to the new array.
