What is the best current answer to the canonical LVM plus software RAID5 issue? FYI, I'm talking about how the kernel's cache needs to correspond to the width of i/o requests. When LVM controls a RAID5 PV, it will cause many differently-sized i/o requests to hit the array in parallel, basically forcing the kernel to flush the cache and rebuild continuously. So, basically my array performs horribly once I create a snapshot volume. I'm using LVM2.1.95.10 + 2.4.20-dm-7. Some older LKML traffic explains the problem, but I haven't found an answer yet.
