I think so too. But again thank you a lot for your help!!!! This community is super.
And the your tip with the share of the root of a disk was usefull too, i dont found that advise anywhere.
So for now i will try a little bit. I have the same computer with the same mainboard but a less powerfull cpu (intel celeron d 2,5 Ghz). I installed Debian 7.9, created a shared folder and installed emby.... and it works. But transcoding works just with 480p@ 420kbps (lol).
So my next step will be to backup my actually server and try a clean debian, and test emby again
I will share my experience.
Btw: After i installed Debian to my second pc, i already missed omv
Last sentence: stop doing to many things at once
Edit: 5.37 am, finally it works, with OMV :), tomorrow i will write a bit
now its time to go to bed
So in tried a lot, but i had no time to answer.
The solution is simple, i didnt use the OMV- Plugin, i just installed it directly via ppa.
And this: http://emby.media/community/in…-files-folders-structure/ is a good guide for folder structure.
