ceph osd pool create {pool-name} {pg-num} [{pgp-num}] [replicated] \
[crush-ruleset-name] [expected-num-objects]
ceph osd pool create {pool-name} {pg-num}  {pgp-num}   erasure \
[erasure-code-profile] [crush-ruleset-name] [expected_num_objects]

ceph osd pool set-quota {pool-name} [max_objects {obj-count}] [max_bytes ytes]

ceph osd pool delete {pool-name} [{pool-name} ——yes-i-really-really-mean-it]

ceph osd pool rename {current-pool-name} {new-pool-name}

9、获取poo参数的值

ceph osd dump | grep 'replicated size'
