117为控制节点和计算节点共用节点上：
nova --debug resize fefe2ba2-69dc-46dc-b337-da2788d94d49 4
117上的compute日志报错：

上述错误说明117上用nova用户执行下述命令有错误：
ssh 192.168.10.114 mkdir -p /var/lib/nova/instances/b4d33c9d-c8b1-49e4-9f50-91f845d4115f
看一下117的用户文件：
vim /etc/passwd
其中
nova:x:162:162:OpenStack Nova Daemons:/var/lib/nova:/sbin/nologin
|
上述信息具体解释请自行查找linuxpasswd相关资料。
此处将nova修改为能够登录的用户：
nova:x:162:162:OpenStack Nova Daemons:/var/lib/nova:/bin/bash
|
ssh-keygen -t rsa
然后再将生成的文件scp到114节点：
scp /var/lib/nova/.ssh/id_rsa.pub root@192.168.10.114:/var/lib/nova/.ssh/authorized_keys |
然后再nova下面执行：ssh 192.168.10.114
报错说当前账户不可用。
登录到114上面查看：
发现nova用户被禁止登录了。
打开：
再次到117上执行发现能登录了：
注意.ssh的所属组和用户必须为root:root，否则无密码登录会失败
再次来验证resize：
成功！
注意在/etc/nova/nova.conf
中有两个与resize相关的配置项：
上述表示在resize之后如果N秒之内不确认resize则自动resize！
