Hi guys,
I thought I had done my research prior to what I'm about to explain, but I might have done something out of order. Here goes:
1) My disk2 had been getting errors in the webGUI and was marked FAILED as SMART overall health. My parity and disk2 were both 2TB drives. Parity has had zero errors since the beginning.
2) I bought new WD 3TB drives with the intention of increasing space since I was replacing drives.
3) I precleared the first 3TB drive, stopped the array, and assigned the 3TB to parity.
4) Parity was re-built
5) This morning, I started the parity check. The check is currently at about 25% and shows that 1700+ errors have been corrected. This is concerning to me as I'm not sure if what is being corrected is "right" since disk2 already had errors.
My question is:
-- Did I screw up by replacing the parity drive BEFORE replacing disk2? If that's the case, am I required to buy a 2TB drive to replace it since my parity is 2TB? I currently have the original 2TB parity disk unassigned and the array has not been written to during this entire process.
Thanks!!
