### Troubleshooting Oracle Linux
#### Docker unmounts `btrfs` filesystem on shutdown
If you're running Docker using the `btrfs` storage engine and you stop the Docker
service, it unmounts the `btrfs` filesystem during the shutdown process. Ensure
that the filesystem is mounted properly before restarting the Docker service.
On Oracle Linux 7, you can use a `systemd.mount` definition and modify the
Docker `systemd.service` to depend on the `btrfs` mount defined in `systemd`.
#### SElinux support on Oracle Linux 7
SElinux must be set to `Permissive` or `Disabled` in `/etc/sysconfig/selinux` to
use the `btrfs` storage engine on Oracle Linux 7.
