Question

Ubuntu14安装ceph正常，
但是采用do-release-upgrade升级到16之后，执行ceph-deploy new node1 报错

我是按照TonyBai 的文章部署的 使用Ceph RBD为Kubernetes集群提供存储卷

创建了cephd账号 免密登陆node1 node2成功
执行 ceph-deploy new node1
报错。

网上给的都是CentOs的解决方案，但我的是Ubuntu，也报错了

报错的第一句“connection detected need for sudo”翻译成中文是：检测到连接需要sudo，sudo是Ubuntu中的超级权限。
所以你可以试试在安装命令前加上sudo命令，如“sudo apt -get ceph”，第一次使用sudo会要求输入密码。
