<pre wrap="">It appears that it's simply not possible to "add" drives to a RAID 1 array.
raidreconf does not support RAID 1.
I had to start from scratch, reinitialize the array with both drives, run
mke2fs, and recopy the data back over from the original drive. It took
another 17 hours to copy everything, (ugh) but it's all up and working fine
now.
Thanks!

Did you properly partition the new drive as type fd (linux raid)?
Maybe you should use mdadm. I have had better luck with it over raidtools.
you would use ;
sfdisk -d /dev/hdh |sfdisk /dev/hde
to clone the partition data, then
mdadm -a /dev/md0 /dev/hde1

I know you can create a raid1 array with only one drive and add the
other drive later, because I have done it.<br>
