Using the Ceph OSD Tree command to view the Ceph cluster, you will find weight and reweight two values
Weight weight and disk capacity, general 1T, value is 1.000, 500G is 0.5
It is related to the capacity of the disk and does not change due to reduced disk available space
It can be set with the following command
Ceph OSD Crush Reweight
The reweight is a v
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
