You said sda was broken, so forget that. Goodness knows how sdd5 managed
to end up being a spare. I think you want `mdadm --assemble /dev/md_d127
--force /dev/sd[bcd]5`. I don't think you can start it read-only but
with a member missing you're not going to get a resync going so this is
unlikely to cause data loss. Still, don't do this if you don't believe
it's the correct answer, and certainly don't blame me if it wastes your
data. Good luck!
Cheers,
John.
