inserting a new disk in a raid 1

inserting a new disk in a raid 1

[Loïc Paillotin]

Hello there.

I recently set  up a linux system. I had only one hard drive by that
time, so I tought that I would configure it for software raid and see
later when I had my second drive. 
I now have my second drive, and I don't have a clue on how to include it
in my raid array. I tried to follow the tutorials ( that is, the raid
HOWTO, but I'm probalby missing someting...... 
thank you in advance,

Does
  raidhotadd /dev/md0 /dev/hdc1

work, where you replace /dev/hdc1 with the name of the partition on
your new drive.
If not, more details are needed, at the very least:

  cat /proc/partitions
  cat /proc/mdstat
