(原)docker的一个“Driver aufs failed to remove...”问题的解决

1.  /var/lib/docker/aufs/mnt下的目录不能乱删! /var/lib/docker/aufs/diff下的目录删了就死了!!!!!
2. 尽量不要用docker tag -f 这个-f恐怕是个大坑其实。。。(其实都是docker自己的bug。。)

问题描述

“Driver aufs failed to remove...”或者

error creating aufs mount to /var/lib/docker/aufs/mnt
/6c1b42ce1a98b1c0f2d2a7f17c196221445f1054566065d4c607e4f1b99930eb-init:
invalid argument

问题的解决:

AUFS is unable to mount the docker container filesystem.

This is either because: the path is already mounted - or - there's a race condition in docker's interaction with AUFS, due to the large amount of existing volumes.

To solve this, try the following:

  1. restart the docker service or daemon and try again.

  2. check mount for aufs mounted on any paths under /var/lib/docker/aufs/. If found, stop docker, then umount them (need sudo).

    example:

$ mount

none on /var/lib/docker/aufs/mnt/55639da9aa959e88765899ac9dc200ccdf363b2f09ea933370cf4f96051b22b9 type aufs (rw,relatime,si=5abf628bd5735419,dio,dirperm1)

then
sudo umount /var/lib/docker/aufs/mnt/55639da9aa959e88765899ac9dc200ccdf363b2f09ea933370cf4f96051b22b9

  1. If that doesn't work, stop docker, then sudo rm -rf /var/lib/docker/aufs. You will lose any existing stopped containers and all images. But this is just about guaranteed to solve the problem.
