ceph osd pool create pool-name pg-num pgp-num replicated crush-rule-name
其中：
pool_name，指定新池的名称。
pg_num，指定池的放置组 (PG) 总数。
pgp_num，指定池的有效放置组数量。将它设置为与 pg_num 相等。该值可省略。
replicated ，指定池的类型为复本池；如果命令中未包含此参数，这是默认值。
crush-rule-name，指定池的 CRUSH 规则集的名称
bash
[root@ceph1 ~ 14:32:49]# ceph osd pool create pool_web 32 32 replicated

ceph osd pool create pool-name pg-num pgp-num erasure erasure-code-profile crush
rule-name
pool-name，指定新池的名称。
pg-num，指定池的放置组 (PG) 总数。
pgp-num，指定池的有效放置组数量。通常而言，这应当与 PG 总数相等。
erasure，指定池的类型是纠删代码池。
erasure-code-profile，指定池使用的纠删代码配置文件的名称。默认情况下，Ceph 使用 default
配置文件。crush-rule-name 是要用于这个池的 CRUSH 规则集的名称。如果不设置，Ceph 将使用纠删代码
池配置文件中定义的规则集。

plugin=jerasure
technique=reed_sol_van创建纠删代码配置文件语法如下：
ceph osd erasure-code-profile set profile-name arguments
可用的参数如下：
k，在不同 OSD 之间拆分的数据区块数量。默认值为 2。
m，数据变得不可用之前可以出现故障的 OSD 数量。默认值为 1。
directory，此可选参数是插件库的位置。默认值为 /usr/lib64/ceph/erasure-code。
plugin，此可选参数定义要使用的纠删代码算法。
crush-failure-domain，此可选参数定义 CRUSH 故障域，它控制区块放置。默认设置为 host，
这样可确保对象的区块放置到不同主机的 OSD 上。如果设置为 osd，则对象的区块可以放置到同一
主机的 OSD 上。如果主机出现故障，则该主机上的所有 OSD 都会出现故障。故障域可用于确保将
区块放置到不同数据中心机架或其他定制的主机上的 OSD 上。
crush-device-class，此可选参数选择仅将这一类别设备支持的 OSD 用于池。典型的类别可能包
括 hdd、ssd 或nvme。
crush-root，此可选参数设置 CRUSH 规则集的根节点。
key=value，插件可以具有对该插件唯一的键值参数。
technique，每个插件提供一组不同的技术来实施不同的算法。
