Please show the examine for the individual partitions of the raid5:

mdadm --examine /dev/sd[a-d]3

{ Replace the '3' if appropriate.  You don't say what partition numbers
your raid5 is on. }

You will need to manually assemble (not create !) your array with a
backup file outside the raid5, and the --invalid-backup option to
abandon the backup file you can't get to.  You will likely have some
unavoidable corruption at the reshape position due to this.
