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/*

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。
