gdisk reports /dev/sdb has a damaged main GPT partition table, and a 
reasonable backup GPT partition table - but with an invalid header. 
(/dev/sda and /dev/sdc are fine.)  So the immediate problem here is 
fixing the GPT partition table.

Strictly, that isn't a RAID1 problem and I don't think it's 
appropriate to ask for comment on that issue on the raid list; people 
here are truly helpful so I'll fix the partition but I could use a 
comment on whether I should then just use the

mdadm  -- manage  ..  --add  ..

commands and whether mdadm needs to be inhibited from taking any 
automatic remedial action.
