EDIT/SOLVED!
Your first parity sync always shows as invalid until it is complete. DO NOT SPIN DOWN THE DRIVE or cancel the parity sync. Just wait for 100% completion.
Hey folks,
I'm out of my depth and hoping for a little help here.
TL;DR: Just added my first parity drive (never had one before now) and it's showing a Parity Invalid error even though the brand new drive tests out fine in SMART and WDDiags.
