I was one of those 4 cases in the part month. I would have certainly
benefited from this when I tried to replace a failing drive on my old
raid-5. But I think actually the redundancy you desired can be
achieved by running a raid-6 at the degraded mode (with 1 missing
drive).
Do I miss something? If this is the case, shouldn't we all
be doing this instead of using the raid-5?
