The Solution:

I guess I am just not used to RAID5 devices.  A disk had gone bad, hence
the error on bootup.  But with one bad disk a RAID5 can still be used, so it
would come up if I manually mounted it.  And yes, I have logging enabled on
all partitions on all my servers, including this one.  My understanding is
that logging doesn't mean you never have to fsck again, it just greatly
decreases the possibility that you might have to.
