13.5. 验证 Ceph MDS 服务
使用 systemctl status
命令验证 Ceph MDS 服务状态。
流程
在所有 Controller 节点上输入以下命令来检查 MDS 容器的状态:
$ systemctl status ceph-mds<@CONTROLLER-HOST>
例如:
$ systemctl status ceph-mds@controller-0.service ceph-mds@controller-0.service - Ceph MDS Loaded: loaded (/etc/systemd/system/ceph-mds@.service; enabled; vendor preset: disabled) Active: active (running) since Tue 2018-09-18 20:11:53 UTC; 6 days ago Main PID: 65066 (conmon) Tasks: 16 (limit: 204320) Memory: 38.2M CGroup: /system.slice/system-ceph\x2dmds.slice/ceph-mds@controller-0.service └─60921 /usr/bin/podman run --rm --net=host --memory=32000m --cpus=4 -v /var/lib/ceph:/var/lib/ceph:z -v /etc/ceph:/etc/ceph:z -v /var/run/ceph:/var/run/ceph:z -v /etc/localtime:/etc/localtime:ro>
