mdadm --examine
only makes sense on a component of an md/raid array, not on the whole
array itself.  So the "mdadm --examine" errors you were getting were
user errors :-)

Everything looks fine except for the "total devices" "working devices"
"active devices" totals, and they aren't used much.  You can probably
fix them with:

  mdadm --stop /dev/md1
  mdadm --assemble /dev/md1 --update=summaries /dev/sd[abcd]3

but before you do that:
  Why do you say the raid5 partition is corrupted?  What are the
  symptoms that caused you to start looking into this?
