We decided to use your OS (Open-E DSS v7) according to the highest evaluation online, but we just started trying to install it on our storage server (super micro) with 80TB ,raid 5, and this is the first foil we face it.

the screen keep on ( open-e "checking source files" ) more than 20 min then got "Error while creating partitions"

Is the open-e cannot handle the bigger size ? or what could be the problem is
