I face a similar problem each time I use KNOPPIX to revive a non-booting
server. It always takes me 10-20 minutes to figure out the right
mdadm incantation to start the md devices. It does not help that mdadm
wants an /etc/mdadm.conf which is on an md device itself, unaccessible.

I wish there were a simple command to find and start all md devices, something
along the lines of:

mdadm --please-find-and-start-all-my-md-devices-please-please-please
or
mdadm --start-all, or whatever.
