Full transparency. I screwed up. Disk 6 is reporting errors on the UI and I miscounted the disk in my array and popped out the wrong disk which was marked offline and emulated. I stopped and restarted the array and popped the wrong disk back in and started a rebuild. 93% later and the same disk 6 is throwing errors again.

I have 2 parity disks and I'm unsure what to do at this point. Is the rebuild going to be corrupted? Does unraid detect these read errors and use parity to fix read error on the fly?

I have ordered a replacement disk, and it will be arriving sometime Tuesday (fingers crossed).

Any advice is greatly appreciated.

Since there are two parity drives they will be used for the rebuild. As long as there are no errors on another disk at the same disk, the rebuilt disk will be correct. Let it finish, then replace the bad disk.

Thanks for the advise. This is exactly what I did and haven't noticed any corrupted files. I've been browsing the disk directly looking for corruption and haven't seen anything yet.
