在mon或client節點上
1.創建池
sudo ceph osd pool create rbd1 100 100
或
sudo ceph osd pool create rbd2 100
2.查看信息
sudo ceph osd dump
3.查看副本數
sudo ceph osd dump | grep "replicated size"
4.刪除池
sudo ceph osd pool delete rbd1 rbd1 --yes-i-really-really-mean-it
5.給池改名稱
sudo ceph osd pool rename rbd1 rbd3
7.設置副本數
sudo ceph osd pool set rbd1 size 3 #默認副本數是3
8.設置pgp_num
sudo ceph osd pool set rbd1 pg_num 110 #pg_num 只能往上調，不能往下調
sudo ceph osd pool set rbd1 pgp_num 110 #等于或小于pg_num
