Well, with answers like this, who needs docker forums?
And what exactly should I back up?

Storage Driver: devicemapper
Hi guys i have centos 6 and I have the problem with Storage Driver: devicemapper I made the step by step of copying docker.service and put it in /etc/systemd/system/docker.service and edit the file and it looks like this
ExecStart=/usr/bin/dockerd -s aufs
And I restart docker but when i ran DOCKER INFO i still have devicemapperā¦ Any ideas?
What do the dockerd logs say?
accionly my docker service stop, and cannot start it because give me error for the root it was on (/lib/systemd/system) so I have to delete the docker.service file in /lib/ and reboot so my Discourse breathe again, so where i have to put it in Centos to make the change of Storage Driver, can I do it in the same address /etc/systemd/system ???
This is my log file, sorry cannot upload the file because IĀ“m new in the community

Copy and modify docker.service actually is not the recommended way to modify docker service, as if newer package ships the file with other changes you wonāt be able to get it.
The recommended way to modify a systemd service is to use the /etc/systemd/systemd/xxx.service.d/yyy.conf
approach.
Take modifying docker parameter for example, one should create the file /etc/systemd/system/docker.service.d/docker.conf
and put below in:
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd --storage-driver=aufs or overlay <plus other options you need>
The directory name under /etc/systemd/system/
must be the service file name plus a .d
suffix.
The file name doesnāt matter as long as it ends with .conf
.
To modify ExecStart
directive you must have a ExecStart=
line to disable the line in the original service definition, or else systemd would think you want to run two ExecStart commands, one is the original one, the other is the new one you just defined.
In such way you ācontainedā your modification of the service to only ```ExecStart`` so if other changes are make in docker.service in newer docker package they wonāt be overridden.
To whom made change to docker service file, remember to run systemctl daemon-reload
before trying to restart docker service. It tells systemd to pick up the change to the service definition file.
If you copy and edit docker.service file in place instead of the recommended docker.service.d/xxx.conf approach, you may also need to run systemctl disable docker ; systemctl enable docker
.
Following your tutorial, I get this error at the restart /etc/init.d/docker restart
:

If I remove the --storage-driver=aufs
option, the restart is OK but no AUFS
The best solution from Ubuntu 14 or 15 is to reinstall a VPS with Ubuntu 16.10 and quickly reinstall Discourse and load a backup.
Hate this !
I would not use 16.10 use the LTS version of Ubuntu. Otherwise you will be forced to upgrade again soon when that is no longer supported. LTS means Long Term Service for a reason.
Hi Kai I do as you said, comment the line ExecStart in the original file that in my case is in /usr/lib/systemd/system and create te file .conf in
/etc/systemd/system/docker.service.d/docker.conf
after doing that I ran systemctl daemon-reload and in that point all seems ok but when I do the restart of the service I have this error

Thanks for the help
Read this line in your log:
ar 06 19:59:41 vps276956.ovh.net docker[6348]: docker: the daemon flag '-s' must follow the 'docker daemon' command.
And how you put the options in docker.conf:
ExecStart=/usr/bin/docker --storage-driver=aufs daemon -H fd://
You need to put the line as:
ExecStart=/usr/bin/docker daemon --storage-driver=aufs -H fd://
Notice the swapped order of daemon and --storage-driver flags.
The last line in your log says aufs storage driver is not supported by docker. Are you sure you are on a distro that supports aufs? Whatās your distro?
Iāve this error too, Iām using a Debian 8.
Iāve commented the ācheck 2ā code to allow the usage of devicemapper
anyway. But I donāt know where this will lead me.
The forum is back, for now!
It usually ends in drive corruption so keep your backups closeā¦
Sorry for the delay my distro is:
[cevmf@server system]$ sudo docker exec app cat /etc/os-release

No that is your OS information in the container.
You need to just run cat /etc/os-release
and uname -a
in your OS shell, not in your container. And send that output.
Ok thanks is:
