Hey,
I have 4 identical disks and 2 set for parity.
I've been looking around and documenting myself about parity but there's something I wasn't able to find... maybe its too obvious but I need to get my mind around it. So the questions are:
1. If you do a parity check today and lose a drive a month later, then the drive restored will have today's data, so you can only "restore" to the last time you did the parity check, is this correct?
2. As I've seen, parity must be always build from start to beginning, with my setup this can take around 20 hours. Can't parity be updated on write?
Thanks
