While this is not a disaster, I wonder if my understanding is
correct? Does this mean mdadm does not scan to assemble as part of
resume? More importantly, how should I rectify the situation like
this? Reboot or simply stop md0 and scan in a live system? Further,
how do I use /dev/sdf1 (that was /dev/sdg1 before this problem)?
zero-superblock and add back to md0?
Of course it does not reassemble the array after a suspend -- the
point of suspend/resume is that the system picks up exactly where it
left off.  Since the array is never torn down, it is not built back
up.  In other words, yanking out drives while suspended isn't really
any different than doing it while running -- not a good idea.
