容器状态变为Removal In Progress的解决方法device or resource busy

1.简介

之前安装好的onlyoffice服务器，今天停电来电之后启动不起来了，容器状态变成了“Removal In Progress”，强制删除又删除不掉，提示“Error response from daemon: container c94c3c5cf8356f483a6bff79a09623635da8b0c5468d6a5086ecf6cb60cf6cca: driver “btrfs” failed to remove root filesystem: Failed to destroy btrfs snapshot /volume1/@docker/btrfs/subvolumes for 54fafd468da290df90bc9481f3701207dbd8af74e38b413a24a934ebe16c727b: device or resource busy”重新也不行，最后通过定位到pid，然后杀死pid解决。

3.步骤

3.1.查看容器状态

root@pan:~# docker ps -a
CONTAINER ID  IMAGE                               COMMAND                  CREATED      STATUS               PORTS  NAMES
c94c3c5cf835  onlyoffice/documentserver:5.5.1.76  "/bin/sh -c /app/ds/…"   12 days ago  Removal In Progress         Onlyoffice-Documentserver-Kodbox

3.2.强制删除容器

root@pan:~# docker rm -f c94c3c5cf835
Error response from daemon: container c94c3c5cf8356f483a6bff79a09623635da8b0c5468d6a5086ecf6cb60cf6cca: driver "btrfs" failed to remove root filesystem: Failed to destroy btrfs snapshot /volume1/@docker/btrfs/subvolumes for 54fafd468da290df90bc9481f3701207dbd8af74e38b413a24a934ebe16c727b: device or resource busy

3.3.定位进程

root@pan:~# grep docker /proc/*/mountinfo |grep 54fafd468da290df90bc9481f3701207dbd8af74e38b413a24a934ebe16c727b

3.4.结束进程并验证

root@pan:~# kill -9 22878 23061 23903 24553 24554 24555 24556 24557 24558 25283 27336
root@pan:~# grep docker /proc/*/mountinfo |grep 54fafd468da290df90bc9481f3701207dbd8af74e38b413a24a934ebe16c727b
grep: /proc/19129/mountinfo: Invalid argument
grep: /proc/19132/mountinfo: Invalid argument
grep: /proc/19135/mountinfo: Invalid argument
grep: /proc/9030/mountinfo: Invalid argument

3.5.删除容器

root@pan:~# docker rm -f Onlyoffice-Documentserver-Kodbox
Onlyoffice-Documentserver-Kodbox
