Hi all - I posted this question to the ceph-user list a few days ago but no one responded, so I thought I'd send it to the devel list too: What happens if I create a pool and associated it with a ruleset (say, set '2', for instance), and then I remove all the rules from set '2'? Similarly, what happens if I add a single rule to ruleset 2 that's size-constrained to pools of size 2 - 3, but then create a replicated pool of size 4 using that ruleset? Is there a fundamental rule that ceph uses (e.g., random selection) to choose osds on which to store the replicas?
