Hendrik,
You might look in the logs to see if they give more detail otherwise I
would try removing the failed device and replacing it with another
that is as close as possible to the same size and see if you can add
it. I have also seen on the duct tape raid I had for a while where I
would have to power cycle the box in order for it to reactivate the
flaky drive. Just a couple of suggestions.
