参考：
Pools — Ceph Documentation
前言：网上的写的乱七八糟不是你抄我就是我抄你 写的完全瞎扯 简直看不下去
官网截图：
#准备
1.查看pool名称
ceph osd lspools
#创建一个pool用于做测试/设置分类
ceph osd pool create pool-demo 6 6
ceph osd pool application enable pool-demo rbd
#查看application类型
ceph osd pool application get pool-demo
#删除pool(需要写两次pool的名称释义确实要删)
ceph osd pool rm pool-demo pool-demo
注：报错原因需要加上： --yes-i-really-really-mean-it
释义我确实要把它给删了
ceph osd pool rm pool-demo pool-demo
报错
Error EPERM: WARNING: this will *PERMANENTLY DESTROY* all data stored in pool pool-demo. If you are *ABSOLUTELY CERTAIN* that is what you want, pass the pool name *twice*, followed by --yes-i-really-really-mean-it.
#再次执行删除
ceph osd pool rm pool-demo pool-demo --yes-i-really-really-mean-it
#再次报错（原因需要将配置改为允许删除ceph默认mon_allow_pool_delete为flase禁止删pool）
ceph osd pool rm pool-demo pool-demo --yes-i-really-really-mean-it
Error EPERM: pool deletion is disabled; you must first set the mon_allow_pool_delete config option to true before you can destroy a pool
#需要通过asock查看mon_allow_pool_delete的设置值 /查看mon_allow_pool_delete设置
ceph --admin-daemon /var/run/ceph/ceph-mon.node-1.asok config show |grep mon_allow_pool_delete
#调整参数
ceph --admin-daemon /var/run/ceph/ceph-mon.node-1.asok config set mon_allow_pool_delete true
注：集群有多个mon其他的mon节点也需要执行同样的操作
#再次执行删除操作(成功)
ceph osd pool rm pool-demo pool-demo --yes-i-really-really-mean-it
注：此参数是临时调整服务器重启参数失效永久生效需要写入配置文件
