About a week or so ago I noticed one of my older 2tb drives had 2 pending sectors on it. So I decided I needed to replace it. So I ordered a new 4tb drive.  I've been using unraid for about 9-10 years and some of my drives are in the old reiserfs filing system. I thought this would be a good time to move all my drives to XFS.  While I was waiting on my new drive to arrive my server started locking up.  I never really figured out exactly why, but this resulted in a few hard shutdowns.  When I would do a parity correction it would show 3-4 errors. I would run it again and the same thing. Finally I was able to get a parity check with 0 errors after cleaning up a few things suggested by a user here.  Well this morning I removed my parity drive (since I only have 6 sata slots) and installed my new 4tb in disk 5 and wanted to clone disk 3.  I was following the directions on the wiki using the rsync command.  All appeared to be going smooth until I started getting read errors on disk 3.  Disk 3 wasn't even the drive I had intended on replacing. It was a 4tb drive that was still in reiserfs so I started with it and was going to do the older tb drive later.  Now I don't know what to do, the rsync command is still running as I type this.  I assume all of the content is being cloned to my new drive since parity was valid?  Do I just let it continue?  Any guidance would be appreciated. I have attached my diagnostics.  Thanks!
