hi, all: In my production environment, each pg is the same pool has different io pressure. The max is 3- 4 times more than min. Currently, max size of each pg is pool.info.target_max_bytes / pg_num. So I think, we could do better. Such as, set different pg target_max_bytes according to their io pressure. Is that make sense? -- Regards, xinze -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
