I can get the new drive into the imsm container but I can’t add it to the raid1 array within that container. I’ve read the man page and can’t see to figure it out. Any help would be greatly appreciated. Using mdadm 3.2.5 on debian squeeze. This should just happen automatically. As soon as you add the device to the container, mdmon notices and adds it to the raid1. However it appears not to have happened... I assume the new drive is exactly the same size as the old drive? Try removing the new device from md127, run "mdadm --zero" on it, then add it back again. Do any messages appear in the kernel logs when you do that? Is "mdmon md127" running?
