I run a small home server with 4 disks and use Drivepool with 2x duplication (haven't figured out how to setup snapraid). Unfortunately, Drivepool reports 3.03TB in "Unusable for duplication". I read the forum and noticed the advice to install the plugin "Drive equalizer", which i did. I have forced re-balancing in Drivepool several times in the hope that this will reduce the unusable space, but it went from 3.05TB to 3.03TB. I'm not sure what I need to do to claim the 3TB back.
I would like to highlight one issue which I had, not sure if relevant. I inserted the Raw 6TB drive into the server and for some reason it converted it to MBR. I realized this late and Drivepool had already transferred a considerable amount of data to the disk. I used EaseUS Partion Master to convert without data loss the MBR drive to GPT. Then I extended the 2TB partition of the drive to the full 5.5TB. I had no problems with my Drivepool after this, but 3TB showed as unusable for duplication.

Advice is much appreciated.
