I think my quick question can only be addressed by developers who have insight into how CRUSH works in "jewel". Our ceph client is using bobtail legacy tunable and in particular, "chooseleaf_vary_r" is set to 0. My question is how it would impact CRUSH and hence performance in deploying "jewel" on the server side and also the experimental "bluestore" backend. Does it only affect data placement or would it actually not find mapping for certain objects and thus cause error?
