comment CentOS 7 Crash on boot
This is not a real solution to your problem, just a pragmatic advice -- try booting from a different medium using a different kernel, and check for hardware problems. If there seem to be none, restore from your backup and save yourself the time tracking this down.

comment Will there be always a pair of same UID and GID?
"by default the UID and the GID are equal for ordinary users" -- actually, this statement is only true if you add "on some popular Linux distributions". Yes, Ubuntu et al. do it this way, but I would consider a common "users" group more of a default.

I doubt that I can get our AFS admins to enable this flag for our huge cell just to let me check it out, but thanks for the pointer!

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.

comment What does mdadm's “spare” number mean?
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.
