TTY报错

sudo: sorry, you must have a tty to run sudo

[node1][DEBUG ] connected to host: node1

[ceph_deploy][ERROR ] RuntimeError: remoteconnection got closed, ensure ``requiretty`` is disabled for node1

解决方案

# visudo

** ERROR: error creating emptyobject store in /var/local/osd0: (13) Permission denied
[admin-node][WARNIN]
[admin-node][ERROR ] RuntimeError: com
mand returned non-zero exitstatus: 1
[ceph_deploy][ERROR ] RuntimeError: Failedto execute command: /usr/sbin/ceph-disk -v activate --mark-init systemd --mount/var/local/osd0

解决方案

在各个节点上给/var/local/osd1/和/var/local/osd1/添加权限

如下：

chmod   /var/local/osd0/

chmod   /var/local/osd0/*

chmod 777  /var/local/osd1/

chmod 777  /var/local/osd1/*

连接超时

解决方案

[root@admin-node my-cluster]#ceph-deploy  osd activatenode1:/var/local/osd1

osd节点起不来

查看节点状态

[root@admin-node my-cluster]# ceph -s

[root@admin-node my-cluster]# ceph osd tree

解决方案

.      关闭防火墙

.      检查ssh无密钥登录配置

.      一般情况下，osd节点启动较慢，等待5分钟左右即可。
