I have a ticket open for this: http://tracker.ceph.com/issues/38745 Please comment there with the health warning you're seeing and any other details so we can figure out why it's happening. I wouldn't reprovision those OSDs yet, until we know why it happens. Also, it's likely that ceph-bluestore-tool can sort it out be adding/removing the db volume.
