The issue was not realizing that a degraded fault-tolerant array would
refuse to mount without being passed an -o degraded option. Yes, it's on
the wiki - but it's on the wiki under *replacing* a device, not in the
FAQ, not in the head of the "multiple devices" section, etc; and no
coherent message is thrown either on the console or in the kernel log
when you do attempt to mount a degraded array without the correct argument.
IMO that's a bug. =)
