So one of my drives Red Balled when I attempted to upgrade to to 6.0b4.  Since there had been so errors or SMART issues what-so-ever (and the fact that I don't have a replacement drive on hand, on order), I attempted to just remove the drive from the Array, re-add the drive and then rebuild.  I started the rebuild last night... it was still running this morning and then again after work today.  It was running at less than 6MB/min most of the time... I finally stopped it cause it was going to take another 50+ hour to finish, so I assumed something was tragically wrong...

 

This error was over and over and over in the log before I stopped it... is this just a tragically BAD disk, or something worse?

Most likely you have a loose or bad cable to the drive.

Thanks, swapped cables and rebuilding at 40-42 MB/sec (through first part of rebuild) which seems more "normal"
