Docker删除容器错误
当我想重新运行容器与另一个卷或更新图像。 我停下来尝试删除容器，但是经常在rm命令上出现乱码
# docker rm containername Error response from daemon: Driver devicemapper failed to remove root filesystem dbe6....f91f: Device is Busy
我需要重新启动docker守护进程来删除容器。

我在红帽主机上遇到过这个问题。 根据报告的问题修复这个问题是升级到一个更新的内核。 作为一个解决scheme，这是不是一个选项，我一直在使用docker rm -f ...仍然抛出错误，但容器得到清理。 比守护进程重启要快得多，干扰也less一些。
我遇到同样的问题， service docker restart几乎总是解决这个问题（重启docker服务）
