无法运行Docker容器由于设备映射器错误 [英] Can't run Docker container due device mapper error

问题描述

我不能在Docker中创建和运行新的容器。
但在同一时间可以运行先前创建的容器。

当我尝试这样做：

  [用户@host〜] docker run --name = fpm-5.3 debian：jessie 
 2014/07/12 07:34:08错误：运行DeviceCreate（createSnapDevice）时出错dm_task_run失败
  

从 docker.log ：

 code> 2014/07/12 05:57:11 POST /v1.12/containers/create?name=fpm-5.3 
 [f56fcb6f] + job create（fpm-5.3）
错误运行DeviceCreate（createSnapDevice）dm_task_run失败
 [f56fcb6f] -job create（fpm-5.3）= ERR（1）
 [error] server.go：1025错误：运行DeviceCreate（createSnapDevice）时出错dm_task_run failed 
 [error] server.go：90 HTTP错误：statusCode = 500运行DeviceCreate（createSnapDevice）的错误dm_task_run失败

但是它们在磁盘上有很多可用空间。

解决方案
以下是Fedora / RHEL系统，因此您需要调整Debian ... 
 ＃systemctl stop docker.service 
＃thin_check / var / lib / docker / devicemapper / devicemapper / metadata 
  
如果没有错误，请继续执行：
 ＃thin_check --clear-needs-check-flag / var / lib / docker / devicemapper / devicemapper / metadata 
＃systemctl start docker.service 
＃docker run --name = fpm-5.3 debian：jessie 
  
 
I just can't create and run new containers in Docker anymore. 
But in the same time a can run previously created containers. 

When I try to do something like this:
[user@host ~ ] docker run --name=fpm-5.3 debian:jessie
2014/07/12 07:34:08 Error: Error running DeviceCreate (createSnapDevice) dm_task_run failed
From docker.log:
2014/07/12 05:57:11 POST /v1.12/containers/create?name=fpm-5.3
[f56fcb6f] +job create(fpm-5.3)
Error running DeviceCreate (createSnapDevice) dm_task_run failed
[f56fcb6f] -job create(fpm-5.3) = ERR (1)
[error] server.go:1025 Error: Error running DeviceCreate (createSnapDevice) dm_task_run failed
[error] server.go:90 HTTP Error: statusCode=500 Error running DeviceCreate (createSnapDevice) dm_task_run failed

But they are a lot of free space on disk.

解决方案
The following is for a Fedora/RHEL system, so you'll need to adjust for Debian...
# systemctl stop docker.service
# thin_check /var/lib/docker/devicemapper/devicemapper/metadata
If there were no errors then proceed with:
# thin_check --clear-needs-check-flag /var/lib/docker/devicemapper/devicemapper/metadata
# systemctl start docker.service
# docker run --name=fpm-5.3 debian:jessie
