July 18, 2025Jul 18 HiAfter a few months of a small number of occasional parity sync errors, I think I've sound the culprit. My parity drive gives an "unknown failure" a few seconds after starting a SMART test.What I'd like to do is remove it and replace it with my current parity 2 drive whilst I look at/RMA the bad drive. As far as I can tell, it should be a case of using the New Config tool whilst keeping the current assignments and only changing the parity drives.I just thought I'd check to see if I'm missing something. Thanks.

July 18, 2025Jul 18 Community Expert To emphasise the point it is perfectly OK to run with parity2 as the only parity drive.Trying to move the current parity drive to be the parity1 drive will force parity to be rebuilt (as they are not interchangeable) and your array would be unprotected until the rebuild completed.

I have 2 parity drives; slot1 = 8To : historically in array for a whileslot2 = 16To : newly added to the array as I wanted to then be able to add another 16To drive as data in arrayCan I safely and forever run only with Parity2 16To and parity1 unassigned ? Thank you for your help !
