So to summarize what happened and what I've learned:
I had a RAID6 array with only 16 out of 18 working drives.
I received an email from mdadm saying another drive failed.
I ran a full offline smart test that completed successfuly.
The drive was in F (failed) state. I used --re-add and mdadm overwrote
the superblock turning it into a spare drive instead of putting the
drive back into slot 10.
I should have used --assemble --force.
Am I correct?
Yes.
However, there have been bugs in --force that would cause it to not
assemble. Also, I believe latest behavior for --re-add would not have
damaged the metadata.
