... or pass --auto to md0.

(If the array is degraded you're stuffed because it's only RAID-0 so
there is no meaningful degraded mode. RAID-0 personally strikes me as
being about as safe as having LVM VGs spanning multiple physical disks
without RAID-based redundancy, because if you lose *any* disk you've
lost the lot, and my faith in the reliability of disks has taken some
severe knocks over the last year... something about losing four disks in
a year after 15 years with no failures has made me a real *convert* to
RAID as well as backups.)
