Hello there, I feel kind of dumb but I'm at my wits ends here on trying to install 3 new hard drives to my array. The three drives are Seagate 16TB HDD Exos hard drives model ST16000NM001G. before replacing one of my array drives that was failing I started with upgrading one of my 2 parity drives. After the rebuild I've attempted to swap/add the other two and I keep getting the error "the parity drive must be the largest". However all drives are the same size and same byte count according to the system. Is there a way to format the drives or trick unraid/linux in to thinking these two are even 100mb smaller so i can use them? The only info I find online is "just use the bigger drive" which clearly when one is formatted as parity it becomes smaller somehow to the system and refuses to let me load the others. Any help is appreciated.

Each parity drive must be at least as large as the largest data drive. Your parity2 disk is smaller.

ahhhh, that's a bummer. thank you for your help.
