April 7, 20251 yr Hello all, My scheduled parity check started this morning, and I just got the notification that one of my drives skyrocketed with errors, then was disabled by Unraid. As of writing, the parity check has 0 sync errors detected. I have a cold spare of the same size and type ready to put in the server, but am unsure exactly how. I am running an LSI 9207-8i card, and have tested that in theory, I can "hot-swap" drives with it. Does that work in Unraid? What is the best way for me to swap in a new drive considering that the parity check is still running? Thanks pearl-diagnostics-20250407-0934.zip pearl-smart-20250407-0938.zip Edited April 7, 20251 yr by Teknicallity Forget small detail
April 7, 20251 yr Community Expert The disk has a lot of pending sectors and failed the SMART test, so it needs to be replaced.
April 12, 20251 yr Author Solution Hopefully this can help someone else in the future. I'm not sure why I was afraid to just cancel the parity check. Ultimately, I just shut down, swapped in the cold spare, then started the array rebuild operation.
