Explanation about min_size is "If a pool makes fewer replicas than this number, CRUSH will NOT select this rule". The max_size is "If a pool makes more replicas than this number, CRUSH will NOT select this rule" Default setting of pool replicate size is 1. Created 2 rules that ruleset0 「min_size = 3」, ruleset1 「min_size = 1」and applied. Then created a new pool named "test" and assume pool "test" will apply ruleset1. But found pool "test" apply ruleset0. Which part I missing？ Thanks a lot for any advice!
