The boot process will hand for three minutes and leave you at a busy box
shell.  This could be improved so that the problem is detected earlier
and the option of getting to the shell (and with suggested commands)
appears earlier.

Once in the shell, you can force the raid to run; this will update the
metadata so that the array can be run degraded automatically in future.
