Calculation formula for PG: Calculation formula for the entire cluster PG The calculation formula for PG in each pool: Total PGs = (TOTAL_NUMBER_OF_OSD *)/Max_replication_count/pool_count The result of the settlement is taken up to the value of the n-th square of the 2. For example, the total number of OSD is 160, the number of copies of the number of 3,pool is also 3, then the result is calculated according to the above formula is 1777.7. Take 2 of the n-th is 2048, then the number
