Hi,
I've just started the replacement process on a WD green drive to a red that had 2 to offlined sectors from a SMART test. The relsilvering is in progress but now I am getting parity CRC errors again. I didn't have these on the old drive, now all of a sudden as soon as I swap out the drive I'm getting heaps of them. 1st question, is this a problem? At the moment I'm going to let the re-silvering process complete first. 2nd question where to from here? I think it's time to get a sata card rather then using the onboard ports. I've had these errors in the past and solved it by changing ports and cables.
Here is the zpool status of the resilvering process:-
And here is the errors i'm seeing in the GUI shell in the footer...

Here is the zpool status of the resilvering process:-
