几个节点可以访问安装的Docker容器 [英] Can several nodes access mounted docker containers

问题描述

如果我将/ var / lib / docker移动到/ mnt / containers /，其中/ mnt / containers
通过glusterfs加载到一个较大的系统，我开始收到这样的错误：

  kernel@192.168 .68.14：Jun 17 16:05:10 stackato-ft9y kernel：[2174.535122] aufs au_xino_set：1176：docker [7572]：I / O错误，创建xino失败（-27）。 
 
 kernel@192.168.68.14：Jun 17 16:05:10 stackato-ft9y kernel：[2174.538613] aufs au_xino_set：1176：docker [7572]：I / O错误，创建xino失败（-27 ）。 
 
 dockerd@192.168.68.14：[error] mount.go：11 [warning]：在卸载之前无法运行auplink：exit status 22 ^ M 
 
 dockerd@192.168 .68.14：文件太大
 
 dockerd@192.168.68.14：[d954f89b] -job create（fence_app_staging_fibo_1a992a98_id-3dd68）= ERR（1）^ M 
 
 dockerd@192.168。 68.14：[error] server.go：1025错误：文件太大^ M 
 
 dockerd@192.168.68.14：[error] server.go：90 HTTP错误：statusCode = 500文件太大
  

在/ var / lib / docker运行时，我看不到这些错误，即使我移动/ var / lib / docker的
内容到不同的本地目录。

我们中的两个人独立地绊倒了 http://osdir.com/ml/linux.file-systems.aufs.user/ 2008-08 / msg00016.html ，但是看起来不是很正确。所以我在这里希望得到驻地码头/ aufs / glusterfs专家的关注。

解决方案

看起来像aufs和glusterfs。您是否尝试使用btrfs或devicemapper？ （使用 -s btrfs 或 -s devicemapper 启动守护程序）

I have a VM running an app that uses about 8 Docker containers.

If I move /var/lib/docker to /mnt/containers/, where /mnt/containers is mounted via glusterfs to a larger system, I start getting errors like this:

kernel@192.168.68.14: Jun 17 16:05:10 stackato-ft9y kernel: [ 2174.535122] aufs au_xino_set:1176:docker[7572]: I/O Error, failed creating xino(-27).

kernel@192.168.68.14: Jun 17 16:05:10 stackato-ft9y kernel: [ 2174.538613] aufs au_xino_set:1176:docker[7572]: I/O Error, failed creating xino(-27).

dockerd@192.168.68.14: [error] mount.go:11 [warning]: couldn't run auplink before unmount: exit status 22^M

dockerd@192.168.68.14: file too large

dockerd@192.168.68.14: [d954f89b] -job create(fence_app_staging_fibo_1a992a98_id-3dd68) = ERR (1)^M

dockerd@192.168.68.14: [error] server.go:1025 Error: file too large^M

dockerd@192.168.68.14: [error] server.go:90 HTTP Error: statusCode=500 file too large

I don't see these errors when running out of /var/lib/docker, or even if I move the contents of /var/lib/docker to a different local directory.

Two of us have independently stumbled on http://osdir.com/ml/linux.file-systems.aufs.user/2008-08/msg00016.html , but that doesn't quite look right. So I'm here hoping to get the attention of the resident docker/aufs/glusterfs experts.

解决方案

Looks like conflict between aufs and glusterfs. Have you tried to use btrfs or devicemapper instead? (start the daemon with -s btrfs or -s devicemapper)
