在mon或client节点上
1.创建池
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.查看副本数
sudo ceph osd dump | grep "replicated size"
4.删除池
sudo ceph osd pool delete rbd1 rbd1 --yes-i-really-really-mean-it
5.给池改名称
sudo ceph osd pool rename rbd1 rbd3
7.设置副本数
sudo ceph osd pool set rbd1 size 3 #默认副本数是3
8.设置pgp_num
sudo ceph osd pool set rbd1 pg_num 110 #pg_num 只能往上调，不能往下调
sudo ceph osd pool set rbd1 pgp_num 110 #等于或小于pg_num
