“设备上没有剩余空间”；即使取出所有容器 [英] "no space left on device" even after removing all containers
问题描述
尝试Docker和Docker Compose时，我突然遇到设备上没有剩余空间的错误。我尝试使用类似问题中建议的方法删除所有内容，但无济于事。
While experimenting with Docker and Docker Compose I suddenly ran into "no space left on device" errors. I've tried to remove everything using methods suggested in similar questions, but to no avail.
我运行的事情：
$ docker-compose rm -v
$ docker volume rm $(docker volume ls -qf dangling=true)
$ docker rmi $(docker images | grep "^<none>" | awk "{print $3}")
$ docker system prune
$ docker container prune
$ docker rm $(docker stop -t=1 $(docker ps -q))
$ docker rmi -f $(docker images -q)
据我所知，现在真的不应该剩下任何东西了。看起来像这样：
As far as I'm aware there really shouldn't be anything left now. And it looks that way:
$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
相同的数量：
$ docker volume ls
DRIVER VOLUME NAME
对于容器：
$ docker container ls
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
不幸的是，我仍然遇到这样的错误：
Unfortunately, I still get errors like this one:
$ docker-compose up

如上所述，我仍在尝试中，所以不确定是否已发布所有相关信息-让我知道您是否需要更多。
As said, I'm still experimenting, so I'm not sure if I've posted all relevant info - let me know if you need more.
任何人都不知道还有什么问题吗？
Anyone any idea what more could be the issue?
推荐答案
问题是 / var / lib / docker 在 / f上ilesystem，它的索引节点用完了。您可以通过运行 df -i / var / lib / docker
The problem is that /var/lib/docker is on the / filesystem, which is running out of inodes. You can check this by running df -i /var/lib/docker
自 / home 的文件系统具有足够的inode和磁盘空间，将Docker的工作目录移动到那里应该会重新运行它。
Since /home's filesystem has sufficient inodes and disk space, moving Docker's working directory there there should get it going again.
（请注意，前提是当前的Docker安装中没有任何有价值的东西。）
(Note that the this assumes there is nothing valuable in the current Docker install.)
首先停止Docker守护进程。在Ubuntu上，运行
First stop the Docker daemon. On Ubuntu, run
sudo service docker stop
然后将旧的 / var / lib / docker 移开：
sudo mv /var/lib/docker /var/lib/docker~
现在在 / home 上创建目录：
sudo mkdir /home/docker
并设置所需的权限：
sudo chmod 0711 /home/docker
将 / var / lib / docker 目录链接到新的工作目录：
Link the /var/lib/docker directory to the new working directory:
sudo ln -s /home/docker /var/lib/docker
然后重新启动Docker守护程序：
Then restart the Docker daemon:
sudo service docker start
然后应该可以再次使用。
Then it should work again.
