You are probably using udev, don't you? Somehow there's presently
no /dev/hdh5, but to remove /dev/hdh5 out of the raid, mdadm needs this
device. There's a workaround, you need to create the device in /dev using
mknod and then you can remove it with mdadm.

We are presently running into a similar problem, which I'm going to describe
on this and hotplug list right now.


Hope it helps,
Bernd
