How to set a flag in docker at the time of start

My docker was running fine but don't know why near about before 32 hours docker daemon stopped .

So i tried to run the daemon again sudo systemctl start docker . Everything was fine . But when i tried to restart the containers using docker restart $(docker ps -aq).

I am getting error in mounting overlay2 . I investigate on google and came to know that overlay2 driver is not supported by my server that's why I am facing this issue.

SO now i have to update the storage driver for docker using flag --storage-driver so i tried sudo systemctl start docker --storage-driver devicemapper but geting error systemctl: unrecognized option '--storage-driver'

Does anyone know how to do it ?

docker version : Docker version 1.13.1, build 6e3bb8e/1.13.1 os : 

NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"

CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="7"

Thanks.

You can set the storage driver with a /etc/docker/daemon.json file that contains the following:

{
  "storage-driver": "devicemapper"
}

I've had much better luck with overlay2, so if you can upgrade your kernel to support the new driver, I'd recommend that instead.
