Troubleshooting Docker Boot errors Error creating overlay Mount To/var/lib/docker/overlay2

Original

Recently running a Redis image in centos7.1 using Docker, the following error occurred:

/usr/bin/docker-current: Error response from daemon: error creating overlay mount to /var/lib/docker/overlay2/65f3c109fb903539820f84856d2725af784f2f03f95b1f0214e34184e4d61ff7-init/merged: invalid argument.See ‘/usr/bin/docker-current run --help‘.

After searching on the internet, a feasible scheme is as follows (change storage driver type, disable SELinux):

Stop the Docker service

systemctl stop docker

Cleaning up the mirror

rm -rf /var/lib/docker

modifying storage types

vi /etc/sysconfig/docker-storage

Change the empty docker_storage_options parameter to overlay:

DOCKER_STORAGE_OPTIONS="--storage-driver overlay"

Disable SELinux

vi /etc/sysconfig/docker

Remove option from –selinux-enabled

You should start Docker.

systemctl start docker

The program was copied from Ysssssssssssssss's blog and the Redis discussion: Error creating overlay mount to .../merged:invalid argument., basically you can determine that SELinux is enabled.
