hello and question I am running omv5 , I set up raid to play 2x 2TB drives + 1 1TB drive , when I set up raid I got total of @ 1.8 TB usable space , So i added a 4 tb drive total 4 drives for raid 5 , and after reshaping I get a total of 2.73 does not seen correct the total from all drives 2x2 +1+4 =@9 TB
please advise
