我有一个正在运行的容器，但是在停止容器并再次启动它之后，它给了我错误：

[ec2-user@ip-10-215-0-163 ~]$ docker start kamailio
Error response from daemon: Cannot start container kamailio: Error getting container 01747db255a74935012442c070945848df706d3880dd6f679e667a3d73461c38 from driver devicemapper: Error mounting '/dev/mapper/docker-202:1-263639-01747db255a74935012442c070945848df706d3880dd6f679e667a3d73461c38' on '/var/lib/docker/devicemapper/mnt/01747db255a74935012442c070945848df706d3880dd6f679e667a3d73461c38': invalid argument

service docker stop
thin_check   /var/lib/docker/devicemapper/devicemapper/metadata

注意 - 如果没有错误，那么

thin_check  --clear-needs-check-flag   /var/lib/docker/devicemapper/devicemapper/metadata
service docker start

然后我们可以启动容器

由于存储驱动程序是容器的设备映射器，因此在我的情况下，容器是从 /dev/dm-1 挂载的。

如果我们这样做 e2fsck -fv /dev/dm-1了，它将恢复容器文件系统，我们可以启动容器。

但仍有一些 inode、文件等被删除，因此容器可能无法正常工作。

寻找更好的答案
