I have a new trial installation with 8 drives in a pool. Two of the drives managed to get duplication on them which I don't want and all of the drives have balancing controlling them which I've tried turning of cause I don't want this either. Furthermore Pool Organization stops halfway and re-measure/checking stops at 7-8%. I just want a Pool of drives with no Duplication and no Balancing/ Can this install be repaired(how) or do I uninstall (help) and start over? Thanks
