I have a RAID 5 array that contains 5 HDD's + 1 hot spare (each is 750 Gb). Drive #1 just died, and the hot spare was automatically brought into the array for a rebuild.
My question is, do I replace the failed drive now, during the rebuild? I have 2 extra HDD's on hand to replace it. I just don't want to do anything that will cause problems with the rebuild.
