I currently have a failed drive that I probably could bring back online by ignoring whatever number triggered the failure count. But baring that for a hot moment, all the drives I have are currently 2TB drives. I want to start replacing them with 4TB drives. I know I can't (specially at the moment) just take out the parity drive with a 4TB drive because of the failure and i can't put the 4tb in for the failed 2tb data.
Could I add an additional 4TB parity drive, leaving the 2TB parity drive. Once the array is back up and 'stable', replace the failed 2TB drive with a new 4tb drive?
Or is there a way I can make this change work? I don't have anymore 2TB drives left floating about. I didn't wanna buy another 2TB drive when replace all of them with larger drives anyways.
