我正在尝试安装和部署ceph集群。由于我没有足够的物理服务器，我使用官方Ubuntu 14.04映像在我的OpenStack上创建了4个VM。我想部署一个带有1个监控节点的集群和3个带有ceph版本0.80.7-0ubuntu0.14.04.1的OSD节点。我按照manual deployment document中的步骤操作，并成功安装了监控节点。但是，在安装OSD节点后，似乎OSD守护程序正在运行但未正确报告给监视节点。当我请求命令down时，osd树总是显示ceph --cluster cephcluster1 osd tree。
以下是可能与我的问题相关的命令和相应结果。

当我通过start ceph-osd cluster=cephcluster1 id=x启动其中一个osd守护进程时记录，其中x是OSD ID：
