Sorry for the rookie question, but I'm looking for clarity with regard to some software RAID terms that different sites and people seem to confuse with each other. I'm wondering if I've been using the wrong terms all along? Are these correct? Stripe width = number of devices in the RAID array (or is it number of bytes in one stripe across all RAID devices?) Chunk size = the smallest amount of data that can be written to each device in the RAID stripe (mdadm's "--chunk" parameter) Stripe size = the number of chunks to put on each device in one pass through the stripe (mdadm's "--size" parameter) Stride = the number of filesystem blocks, per single stripe across all devices. So... (--chunk=32kiB)*(--size=4)*(stripe width of 3) = (stride of 96) assuming 4kiB fileystem blocks? Any clarity would be much appreciated.
