Hi Dan, I'm using Emperor (0.72). Though I would think CRUSH maps have not changed that much btw versions? > That sounds bizarre to me, and I can't reproduce it.

Looks like you would have at least rack/server/drive. Would that make the difference? > As far as I've experienced, an entry in the crush map with a _crush_ weight > of zero is equivalent to that entry not being in the map.

Is the crush weight the second column of ceph osd tree ? I'll have to pay attention to that next time I drain a node. Thanks for investigating!
