[ceph-users] weight_set array in Ceph CRUSH

Hi, I have a confusion regarding a struct data type in Ceph CRUSH source code. Header fie in here https://github.com/ceph/ceph/blob/master/src/crush/crush.h If you see below. there is a struct data type namely _weight_set_. What I have understood going through different CRUSH maps, this _weight_set_ array should be a 2D array, am I right? struct crush_choose_arg { __s32 *ids; /*!< values to use instead of items */ __u32 ids_size; /*!< size of the __ids__ array */ struct crush_weight_set *weight_set; /*!< weight replacements for a given position */ __u32 weight_set_positions; }; BR Bobby
