Hi all, In the current implementation, the base pool's snap info is well propagated to the cache pool. However, this is not vice verse. When creating a pool snap on the cache pool, this information is not shared with the base. And it could potentially be overwritten by the later snap operations on the base pool. Should we allow pool snap operations on the cache pool? Another question is that is it safe to clear all the snap infos on the cache pool when removing the cache tiering? This seems ok to me if the base and cache pools' snap infos are identical. I'm asking this because if the snap infos are not cleared on the cache pool, it prevents us from using this pool as a cache pool again. -- 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
