Read up on the md-faulty device.
Got any links to this? As I said, we know how to set the device as
faulty, but I'm not convinced this is a good simulation of a drive that
fails (times out, becomes unresponsive, etc.)

I hope that works for you. Please feel free to pass these instructions

I'm not sure I understand what you're saying about mounting /dev, /proc

just run:
mount --bind /dev /newroot/dev
mount -t proc /proc /newroot/proc

btw, be sure to add auto=yes to the ARRAY lines in /etc/mdadm.conf

would be correct in pointing to /dev/sda.
Sound opinions welcome.

this is not really important, but you should have used the raid devices
so nothing happens.
Does anybody see a solution or see what I'm missing? Help would be
appreciated. I can't believe this is so complicated! :(

Am I right in the assumption that your NASes are Linux boxes? :)
Did you take a look at Linux Network block devices (nbd/enbd)? They
might be what you need: you'd get a raw device on
theoretical reason why one choice would be better than the other --
in terms of security, performance, memory usage, etc.
A knowledgeable answer would be appreciated. Thanks in advance.
