Currently I plan to build a 5x500GB raid-6 from new drives and restore the data from the backup. I'm keeping the original set of 4 offline just in case I need to recover anything from it. I still have a couple of questions I hope someone can help me with. 1. Can I still add the original sde back to the raid-5? While I was doing rebuilding, I believe some files were modified by the OS and the old sde would be out of sync. 2. Quite a few people talked about "scrubbing" the raid, can someone point me to somewhere I can read more about it? I'm new to the list. I tried googling and reading the list wiki and had a hard time finding a tutorial for setting this up. Regards, DS
