Ubuntu12.04上的Docker守护进程启动错误

Question

我遵循了Ubuntu 12.04安装指南中给出的所有步骤

但是，当启动docker守护进程时，它会失败：

~  sudo docker -d
[sudo] password for prat0318:
2014/06/10 02:26:34 docker daemon: 1.0.0 63fe64c; execdriver: native; graphdriver:

[29daee74] -job initserver() = ERR (1)
2014/06/10 02:26:34 Error running DeviceCreate (createPool) dm_task_run failed

Ubuntu版本(这是一个数字海洋液滴)：

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 12.04.4 LTS

我甚至尝试过从vps重新启动和注销/登录，但都没有效果。

更新:为了帮助那些仍然面临这一问题的人，我在前面提交了一个吉特布问题，对它进行了实质性的讨论。

很可能您的Docker守护进程已经在运行。

检查守护进程服务是否正在运行：

thomas@tmp:~$ sudo service docker status
docker start/running, process 2593

请Docker守护进程报告其版本：

thomas@tmp:~# sudo docker version
Client version: 1.0.0
Client API version: 1.12
Go version (client): go1.2.1
Git commit (client): 63fe64c
Server version: 1.0.0
Server API version: 1.12
Go version (server): go1.2.1
Git commit (server): 63fe64c
