无法移除闲置的docker容器.存储驱动程序:btrfs

我在移除死容器时遇到问题。当我试图移除容器时，我得到：

$ docker rm -f d1dd3082f7bb
Error response from daemon: Unable to remove filesystem for d1dd3082f7bbfc2310e497d0af47d51a8ca4e6e90a0d565a85d033f96a12325f: remove /var/lib/docker/containers/d1dd3082f7bbfc2310e497d0af47d51a8ca4e6e90a0d565a85d033f96a12325f/shm: device or resource busy

以前从未遇到过这样的问题。关于当前设置的一些信息：

如何安全地移除它们？

忘了提一下，这些容器是由docker swarm和compose管理的。

$ docker ps -a

增加了对死集装箱的码头检查，检查输出

$ docker inspect 4a1193af7710
