Hi,
I just have 3 HDDs as a JBOD in my OMV. I played with some plugins, but many of them didn't work (I got an error while activating them), but most of them I've deinstalled actually. Up to 4 month ago the HDDs went to sleep. I can't tell, when it changed, but i think it was while updating to 2.x. Now no HDD goes to sleep, even if I change the power down time. I set it on 10 Minutes, but i think every 5 minutes something access to the HDDs (every of my HDDs got an own LED, and all of them are blinking once every approx 5 minutes). Even the new attached HDD with no shared folder or something! first i thought it could be the Plex Media Server (btw: it's damn slow while transcoding on a X2 4600+, the CPU has load of 100%, but the movie is like a flipbook), but even after deinstalling it, something access to the HDD. Actually I'm pissed of very much and I'm planning to install WSE2012R2 on my machine. Maybe you have some hints how i can solve my problem?
