启动守护进程

#要在Ceph节点上启动特定的守护程序实例(确认节点上有此进程)，请执行以下操作之一：

sudo systemctl start ceph-osd@{id}
sudo systemctl start ceph-mon@{hostname}
sudo systemctl start ceph-mds@{hostname}

停止守护进程

#要在Ceph节点上停止特定的守护程序实例(确认节点上有此进程)，请执行以下操作之一：

sudo systemctl stop ceph-osd@{id}
sudo systemctl stop ceph-mon@{hostname}
sudo systemctl stop ceph-mds@{hostname}
