Thank.

I know what the 'busy' thing is now.
sdo1 appears the be the 'same' as some other device in some way.

Also it looks like you might have turned some drives into spares
unintentionally, though I'm not sure

Could you pleas send "mdadm --examine" output for all of these drives and
I'll have a look.

Thanks,
