I've been working on getting my new box up and running after having accidentally installed 32-bit 1.x, I'm up and running on 64-bit 2.x but the ZFS plugin isn't available. I've got the latest OMV-Extras installed, here's my system basics:
i5-2500K, 4GB
Debian 7.11
Kernet 3.16 Backports
OMV 2.2.14
OMV Extras 2.13.9
The plugin simply isn't there in the plugins screen. I read that the plugin was moved into the main repo from it's own, but it's still not showing up, even with the testing repo enabled.
