I experienced a physical drive failure on my R6 RAID 5 and went to replace it. Not wanting to get the wrong drive, I checked with the table you provided to see those that are compatible because this is the first drive failure I have had since I have been running a RAID 5 for over 6 years now. The list first shows Hitachi drives with #1 being a 1TB and having a 32 MB buffer. In fact, it is the ONLY drive on the entire list that has a 32MB buffer, but it is no longer in production. So I bought the only other 1TB drive on the list, which is #8, a Toshiba with all the same attributes as the original Hitachi 1TB, EXCEPT it has a 64MB buffer.
I started the rebuild tonight following instructions provided by Promise, but I realize it will likely run until morning. My question is this: Am I going to see a good rebuild completed tomorrow or a mess because of the different buffer sizes? And if it does not rebuild, are there ANY 1TB drives out there that will fit into my RAID 5 flawlessly? I should not have to buy a whole new set because one drive failed, right?
P.S. It has already been running 45 minutes and still shows 0% on the progress bar. I'm hoping that is because it first must "format" the new drive for its participation in the RAID 5?
