@jon-fuentes The disk space error message is an incorrect one. The issue is partclone is not passing enough information back to FOG on why it aborted. The answer is probably sprawled across the partclone screen just above the screen shot you provided. The fog service only can tell that partclone aborted for some reason and the “guess” was the hard disk on the fog server is full. Rerun your imaging again and watch what message partclone displays.
Also you might consider upgrading your version of FOG sooner or later. FOG 1.5.1 is waiting for release so you might want to hold off for a bit to upgrade, but you should upgrade once 1.5.1 there are quite a few disk imaging fixes in 1.4.4 with a handful more in 1.5.1. So you should consider upgrading to make your imaging a bit smoother.
