union-fs?

Hello guys,

I am looking for a way to merge serveral HD’s into one virtual HD. (i am looking at union-fs)

Any advice?

Maybe mhddfs (if available for arm?)

Just remember it would be like a stripe of drives…which means loss of any one means loss of all data

Right now i am trying out unionfs-fuse (just playing around with it). It seems so work fine. (easy install, easy config). I am not sure but i don’t think i can loose all data on all drives at once in case of a write-failure.
