【ceph】删除pool

简介
删除pool时出现问题，以下为详细解决过程

[root@ceph-object-01 my-cluster]# ceph osd pool rm .log  --yes-i-really-really-mean-it
Error EPERM: WARNING: this will *PERMANENTLY DESTROY* all data stored in pool .log.  If you are *ABSOLUTELY CERTAIN* that is what you want, pass the pool name *twice*, followed by --yes-i-really-really-mean-it.
[root@ceph-object-01 my-cluster]# ceph osd pool rm .log .log  --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

查看删除pool权限

[root@ceph-object-01 my-cluster]# ceph --show-config |grep mon_allow_pool_delete
mon_allow_pool_delete = false

开启删除pool权限

vim ceph.conf
mon_allow_pool_delete = true

覆盖配置文件

ceph-deploy --overwrite-conf admin ceph-object-01 ceph-object-02 ceph-object-03

重启mon|mgr进程
