MDADM RAID5 listing active drives as spares

I have a mdadm RAID5 of 6 sata drives that was working fine until about a week ago when it was getting slow reads, but wrote fine. After some looking around, and help on IRC, we figured it was the sata card I had of the drives on. When I plugged the new card in, it was working, and rebuilding. I woke up this morning and it seems something happened and now 2 drives are listed as spares. I did start the raid with --assemble --force after putting the new card in.

This is a pastebin of mdadm --examine --scan and mdadm --examine /dev/sd[bcdefg]1

Presumably the drive got an IO error and we removed from the array.

kernel logs?

Why do people like pastebin so much?? Why don't you just paste the text you
want to share directly into the email??? It is not like it is big or
anything....
