I have a QNAP unRaid system. It's a TS 453be with 4 slots. I have 2x 14TB with one being parity, Ix 4TB, 1x 1TB ssd for cache. I wanted to upgraded my 4TB to a 12 TB & followed https://docs.unraid.net/legacy/FAQ/replacing-a-data-drive/
Now after install of 12 TB drive, I can't start the array because of too many errors.
Please advise & thanks
