**集群操作**

#### **高层运作** ####

高级群集操作主要包括使用ceph服务启动，停止和重新启动群集。检查集群的运行状况；以及监视运行中的集群。

 *  [监控集群][Link 3]
 *  [监视OSD和PG][OSD_PG]
 *  [用户管理][Link 4]
 *  [修复PG不一致][PG]

#### **数据放置** ####

一旦集群启动并运行，就可以开始处理数据放置。Ceph支持PB级数据存储集群，其存储池和放置组使用Ceph的CRUSH算法在整个集群中分配数据。

 *  [粉碎地图][Link 11]
 *  [手动编辑CRUSH地图][CRUSH]

#### **低层运作** ####

低级集群操作包括启动，停止和重新启动集群中的特定守护程序。更改特定守护程序或子系统的设置；并且，将守护程序添加到集群或从集群中删除守护程序。低级操作的最常见用例包括扩大或缩小Ceph集群以及用新硬件替换旧硬件或出现故障的硬件。

#### **故障排除** ####

Ceph仍处于领先地位，因此您可能会遇到需要评估Ceph配置并修改日志记录和调试设置以识别和纠正群集遇到的问题的情况。
