1.?添加池
```shell
# ceph osd pool create ssdpool 256 256
# ceph osd pool create hddpool 256 256
## 列出池
# ceph osd lspools
1 .mgr
2 ssdpool
3 hddpool
```
2. 創(chuàng)建規(guī)則以使用該設(shè)備
```shell
# ceph osd crush rule create-replicated ssd default host ssd
# ceph osd crush rule create-replicated hdd default host hdd
## 查看池規(guī)則
# ceph osd crush rule ls
replicated_rule
ssd
hdd
```
3. 將池設(shè)置為使用規(guī)則
```shell
ceph osd pool set ssdpool crush_rule ssd
ceph osd pool set hddpool crush_rule hdd
```
4. 刪除池
```shell
## 刪除池時，池的名字要輸入2次
# ceph osd pool rm testpool --yes-i-really-really-mean-it
Error EPERM: WARNING: this will *PERMANENTLY DESTROY* all data stored in pool testpool. ?If you are *ABSOLUTELY CERTAIN* that is what you want, pass the pool name *twice*, followed by --yes-i-really-really-mean-it.

# ceph osd pool rm testpool testpool --yes-i-really-really-mean-it
```
