Hello Boris,
I'm in a similar search for a scalable and resilient solution. So far I like glusterfs, relatively easy to setup, no meta-server required, decent performance, but I haven't tested it thoroughly. Been playing with their latest beta release in a raid0+1 setup; haven't managed to lose any data yet.
I'll also be interested in opinions from other people.

Nux,
Thanks for your response. I have looked into glusterfs and I like it too. I just haven't found the hardware to try it on.
I "tested" it on 4 VMs.. The performance was crap as expected, but wanted to see how it behaves when I suddenly remove a node from the setup and so on. (it went well, the setup froze for a second but after that kept working at normal parameters)
What is RAID0+1? The flat RAID with one parity disk?
No, I should've rephrased this, I meant the likes of raid10, of course, in Glusterfs "speak". Basically I had 2 pairs of replicated nodes and files stripped across all this. I even ran a VM on top of this VM based glusterfs setup.. not the speediest VM, but was usable. :-)
