November 17, 20169 yr I'm running 6.2.4 and I've got 1 parity drive and 5 disk drives in the array. One of the disks has been reporting read errors. The new drive I purchased I want to use as the parity drive and shift the parity drive to replace the bad disk. I've moved all files off the bad disk to other disks since I had room. What's the best way to proceed on this? I was thinking of doing the following: Stop and Power down the array. Remove parity drive. Add new drive. Power on array and set new drive as parity disk. Rebuild parity. Stop and Power down the array. Remove bad drive. Add previous parity drive. Power on array and set previous parity drive to disk # vacated by the bad drive. But since parity will rebuild and there is nothing currently on the bad disk anyway, can I simply combine it and do the following instead: Stop and Power down the array. Remove bad drive. Add new drive. Power on array and set existing parity as disk # vacated by bad drive and set new drive to parity. Rebuild parity.
