Hi all, The macro is defined in ec.c file as the following statement. #define EC_MAX_NODES (EC_MAX_FRAGMENTS + ((EC_MAX_FRAGMENTS - 1) / 2)) But according to my understanding and the comments above the statement, it seems that (EC_MAX_FRAGMENTS - 1) should not be divided by 2. The number of the redundancy should be less than the number of fragment, instead of half of it.
