The array did not start. It did not start when I booted up the machine.

I've no idea. Where should I look?

The machine is not directly on the Internet, cannot send mail to the
Internet, and does not have reportbug installed. Anyway, I can rarely be
bothered to go through the rigamarole of running reportbug in a way to
output things to a file and mail that manually, just on the off chance
that there's a reportbug script for the package in question.
