Hi to all i've read that with md is possible to create non-standard RAID layouts like RAID10 but without being forced to use an even number of disks to create the mirrors (like a standard RAID10) So, would be possible to create a 4-disks RAID10, with redundancy set to 3 (I need to survive up to to ANY 2 disks failures, like with RAID6) ? I think it would be something like the following? A1 A1 A1 A2 A2 A2 A3 A3 A3 A4 A4 A4 Currently, when i need something similar, i use a 3-way RAID1 with LVM on top of it to aggregate multiple mirrors in one bigger volume, but this requires 3 drives for each mirror. Other solutions ? I don't wan't to use any parity raid this time. (wasting space with a 3way mirror and LVM on top would be ok, is nothing better is available) The raid *must* be scalable, i need to grow it on-the-fly by adding one or more disks, when needed.
