January 15, 201610 yr last time i completed a parity check was when i converted my drives to xfs i havent complete a parity check since and its been about 2-3 months now. im trying to complete a parity now but i keep getting errors it will eventually fail and red ball a drive or half of my array for some reason i the run new config to put things back and everything goes back to valid i stopped trying to complete the parity check for a few days and my arrary was still valid mover still worked fine and no errors when transferring from cache to protected array so i tried parity check again and same thing happens again with errors and redballs parity check also goes at 5mb so i know then its going to fail i bought new breakout and sata cables in case that was the issue but nope system diag is attached EDIT: i also tried building a new parity drive but still goes at 5mb and then continue to fails media-diagnostics-20160115-0108.zip
