Question

当我想用其他卷重新运行容器或更新映像时。我停下来尝试删除容器，但通常是rm命令

上的geterror

# docker rm containername

Error response from daemon: Driver devicemapper failed to remove root filesystem dbe6....f91f: Device is Busy

我需要重启docker守护进程才能删除容器。

Answer 1

我在Red Hat主机上遇到过这个问题。根据报告的问题修复此问题是升级到更新的内核。作为一个不可选择的地方的解决方法，我一直在使用docker rm -f ...，它仍然会抛出错误，但容器会被清理干净。比重启守护进程更快，更少侵入。

Answer 2

我遇到了同样的问题，import csv a={'1':{'0.9'}, '2':{'0.6'},'3':{'0.5'}} b = dict(zip(a.keys(), map(lambda x: next(iter(x)), a.values()))) with open('new_file','w') as f: writer = csv.writer(f) writer.writerows(b.items())几乎总能解决问题。（重启docker服务）
