Confirmed - i tried replicate + stripe, stripe + replicate and replicate +
distribute and all works fine, though i found out that with 4 nodes the setup
like this performs best, giving me about 80mb/sek write, 100mb/sek read with
gbit connection:

volume mirror-0
    type cluster/replicate
    subvolumes node01 node02

volume mirror-1
    type cluster/replicate
    subvolumes node03 node04

volume stripe-0
    type cluster/stripe
    subvolumes mirror-0 mirror-1
