Raid 10 is a complicated subject what with near and far, and whether it will grow, etc etc. I'm planning to raid-10 my swap partition, and while it doesn't matter in the slightest because destroying and recreating will be no hassle for swap, I'd like to understand what's going on. If I remember correctly, there was a thread a little while back on growing a raid-10? And you can't (for certain values of "can't" :-) do it? Where's the best place to find info about near, far and offset layouts? I seem to remember "man md", but is there anywhere better? To give you an idea of what I'm planning, I've currently got 2 x 4TB drives that will have a swap partition. I know if I raid-10 that it's effectively just a raid-1 mirror, but I intend to add a third, and then probably a fourth, drive. Can you do that? What will the result be? And for swap especially, does anybody know if I should optimise for read or write - common sense says they're equally important but as a scientist I know common sense is not to be trusted :-) Of course, all this will end up on the wiki :-) Cheers, Wol -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
