Hi, I would prob. start by figuring out exactly what pg are stuck unclean.
You can do 'ceph pg dump | grep unclean' to get that info - then if your theory holds you should be able to verify the disk(s) in question. I cannot see any _too_full so am curious what could be the cause. You can also always adjust the weights manually if needed ( http://ceph.com/docs/master/rados/operations/control/#osd-subsystem ) with the (re)weight cmd.
