I appreciate everyone's help, especially Neil Brown. I was able to change the metadata from 0.90 to 1.0 without losing any data (which was good since it would have take 20+ hours to restore). I even tried changing my three RAID1 arrays to version 1.00 but stopped at my boot partition. I now believe I remember reading that grub2 only understands version 0.90; regardless, it wouldn't boot with it changed to 1.0 so I changed it back to 0.90 and all is good. I got rid of the erroneous super block on the fourth drive and the arrays are automatically assembled on boot without intervention. Much obliged for all the quick responses. Now I just wait for my replacement drive from Hitachi and things will be back to 100%.
