3.2.9. 检查 Ceph Monitor 状态

流程

1. 要显示 monitor map，请执行以下操作：

   [root@mon ~]# ceph mon stat

   Copy to Clipboard Toggle word wrap

   或者

   [root@mon ~]# ceph mon dump

   Copy to Clipboard Toggle word wrap

2. 要检查存储集群的仲裁状态，请执行以下操作：

   [root@mon ~]# ceph quorum_status -f json-pretty

   Copy to Clipboard Toggle word wrap

   Ceph 将返回仲裁状态。由三个监控器组成的 Red Hat Ceph Storage 集群可能会返回以下内容：

   Example
