docker-compose down

报错：
Error response from daemon: driver "overlay" failed to remove root filesystem for <some-id>: 
remove /data1/docker/overlay/<some-id>/merged: device or resource busy

grep <some-id> /proc/*/mountinfo

• 一般通过查找可以找到PID。
• 根据这个PID发现是一个/usr/libexec/colord的程序在使用。
• 查了一下程序的信息，发现确实是将之前删除不了的目录写在了mountinfo中。
• 找到进程就好办了。直接将这个进程kill掉。
• 重新执行docker-compose down，提示删除成功。

1、现象复现，提示device or resource busy

docker rm -f recom-engine-service
Error response from daemon: driver “overlay2” failed to remove root filesystem for 68222175a2ec896c9a084c5fb87966588cf2ba644e6f8b6f326373fea022d153: remove /data0/docker/overlay2/ce44e5ab1eb91fe52acb87c8e37c140d4240be01d2d4afd12b22442cb86f761b/merged: device or resource busy

2、查找占用目录的进程

grep ce44e5ab1eb91fe52acb87c8e37c140d4240be01d2d4afd12b22442cb86f761b /proc/*/mounts

3、杀掉进程

kill -9 189695

4、继续操作删除，成功

docker rm -f recom-engine-service
