linux - Docker:创建aufs挂载到/var/lib/docker/aufs/mnt/15396ee0f38d161382f104e11c94b6ca0efafe10f9952e1dfba4f548009fbe59-init时出错:参数无效

Question

我正在尝试构建一个 Docker 虚拟机并不断收到此错误:

error creating aufs mount to /var/lib/docker/aufs/mnt/15396ee0f38d161382f104e11c94b6ca0efafe10f9952e1dfba4f548009fbe59-init: invalid argument

我在 Ubuntu 14 上使用 Docker 版本 1.11.2，构建 b9f10c9。这是 Dockerimage 的代码:

我该如何解决这个安装问题？

编辑:在 live usb 上运行主机操作系统，特别是 ubuntu，会导致这个问题吗？

我也尝试了 Error: "error creating aufs mount to" when building dockerfile 的建议但它没有用。

Live usb 几乎可以肯定不是 ext4，也不是其他受支持的文件系统之一。它很可能正在覆盖，我认为您不能在 overlayfs 之上安装 overlayfs。

您可以使用 mount 命令查找当前文件系统的/var/lib/docker。例如。在我的本地环境中(我是符号链接(symbolic link)的，因此我的路径和文件中的额外点显示在 homelv 中):

# df /var/lib/docker/.
Filesystem                               1K-blocks      Used Available Use% Mounted on
/dev/mapper/bmitch--vg-homelv 720798904 437701948 246459468  64% /home

# mount | grep /dev/mapper/bmitch
/dev/mapper/bmitch--vg-homelv on /home type ext4 (rw,relatime,data=ordered)

注意挂载输出中的“type ext4”。

Docker 有一个列表 supported backing filesystems :

• overlay2, overlay: xfs with ftype=1, ext4
• aufs: xfs, ext4
• devicemapper: direct-lvm
• btrfs: btrfs
• zfs: zfs
• vfs: any filesystem
