10.3. 查看 Ceph 文件系统快照镜像的指标

流程

1. 获取 asok 文件的名称。asok 文件可用，镜像守护进程正在运行，并位于 cephadm shell 中的 /var/run/ceph/ 中。

2. 在运行 CephFS 镜像守护进程的节点上运行以下命令来检查镜像指标和同步状态。

   语法

   [ceph: root@mirror-host01 /]# ceph --admin-daemon ASOK_FILE_NAME counter dump

   示例

   [ceph: root@mirror-host01 /]# ceph --admin-daemon ceph-client.cephfs-mirror.ceph1-hk-n-0mfqao-node7.pnbrlu.2.93909288073464.asok counter dump
