comment How to automatically start and shut down VirtualBox machines?
Two reasons: First, as stated in the original question, I did not want to alter the heavily modified guest OS if it wasn't really necessary. Secondly, and more importantly, this was intended to provide a clean way to automatically shut down all running VMs if the host was shut down.

I think the key information from the wiki page you linked to is this: "For raid5 there is an optimisation: mdadm takes one of the disks and marks it as 'spare'; it then creates the array in degraded mode." -- this would fit nicely with the observation made by derobert in the comments above. Apart from that, I'm afraid you misunderstood my question: I did not want to have 5 drives worth of space. Mentioning the 2 TB was just an observation.

@derobert, you are right: After the initial rebuild was finished, I got ARRAY /dev/md0 metadata=1.2 spares=1 name=[...] from mdadm --detail --scan and an equivalent info from /proc/mdstat.

Well, unfortunately "link rot" is a huge problem in those cases... I think, for posterity, the following two lines catch the basic idea behind your Link: It's creating a service that uses VBoxHeadless -s %i to start and VBoxManage controlvm %i savestate to stop the VM.
