No, I didn't even realize what I'd done until I
went to mkraid the new raid and sdd1 wasn't
ready.

It finished...

   Personalities : [raid0] [raid1]
   md1 : active raid0 sdd1[2] sdc1[1] sdb1[0]
         215479488 blocks 32k chunks

   md0 : active raid1 hda1[0]
         117218176 blocks [2/1] [U_]

lsraid -a /dev/md0 gives me this:

   [dev 9, 0] /dev/md0   ####bunch of numbers#### online
   [dev 3, 1] /dev/hda1  ####bunch of numbers#### good
   [dev ?, ?] (unknown)  ####bunch of numbers#### missing

So... the drive I destroyed is "missing" in action.
What can I do to recreate the (reiserfs) raid?

I'm copying everything off onto the new drives now.

Thankfully I was protected, at least in part,
from total loss.
