None of your OSDs have been blacklisted. 2 of your MDSes have been, but that means that they either went down or were so laggy as to be useless. If they were laggy, then they will eventually find out and restart themselves, at which point they will be identified as a different MDS and won't be blacklisted.
This doesn't mean there's anything wrong with your OSDs, though!
