there is storage driver migrations guide although I didn't try
try this

Guys I moved to OverlayFS. So far so good in Kernel 4.8

Thanks everyone!

Hi, is the plugin available also for omv running on raspberry pi2?
Refreshing plugins I have this error:

There's no secret involved. The steps are same of the devicemapper tuturial, but use "overlay" instead of "devicemapper" in DOCKER_OPTS

Before doing it... I backed up all my images with the "docker save" command (to load them later) and wrote down all my configs of containers, that I had to recreate later.

Thanks!
one thing though, what made you decide to use overlay instead of devicemapper?

It will probably the next default storage driver for docker, as far as I've read on the net.

Also, the fact that only kernel 4+ supports it makes it feel like more cunning edge tech

hello after installing the docker ui plugin when i click docker in left menu i get an error:

Error: "couldn't connect to host" - Code: 7
Fout #0:exception 'OMVModuleDockerException' with message 'Error: "couldn't connect to host" - Code: 7' in /usr/share/omvdocker/Utils.php:63Stack trace:#0 /usr/share/omvdocker/Utils.php(180): OMVModuleDockerUtil::doApiCall('http://localhos...')#1 /usr/share/openmediavault/engined/rpc/docker.inc(354): OMVModuleDockerUtil::getContainers('42005')#2 [internal function]: OMVRpcServiceDocker->getContainers(Array, Array)#3 /usr/share/php/openmediavault/rpcservice.inc(125): call_user_func_array(Array, Array)#4 /usr/share/php/openmediavault/rpc.inc(79): OMVRpcServiceAbstract->callMethod('getContainers', Array, Array)#5 /usr/sbin/omv-engined(500): OMVRpc::exec('Docker', 'getContainers', Array, Array, 1)#6 {main}

any idea what i should do?

Have you changed the default storage driver from aufs? The directory permissions are ok?

hi, thanks for helping,

but i don't know what you mean with the aufs driver and which directory needs permissions?

Strange, if it is the first time you run Docker and your kernel is 3.16, it should run.

I'll let the experts take from here...

Oops, and no experts available?

For the moment there isnt much on my omv, except my pictures. Would it be better to get OMV 3?

Quote from nicjo814

Try to restart the docker service. "service docker stop" followed by "service docker start"

Thanks a lot man, that did it indeed!

Is it as easy to import my hdd's as in FreeNAS? in OMV i use 2 discs mirrored.?

there is omv-zfs plugin in both OMV 2.x 3.x and support importing disk
if you can import zfs disk in OMV 2.x, I'm sure it will works in 3.x

I'm currently fixing omv-zfs and omv-zfs 3.x has little bug
Do not use omv NFS share for zfs filesystem (but workaround is exist)
