Dear Ferenc,

Many thanks for your reply. Regarding $subj, i know about ddraid. I found it 
before my post. Unfortunatelly, this project is still in alpha (not 
production quality) and seems to be abandoned or freezed ... 

Coda is looking like a dead project, it is moving very slowly (unpredictable 
development on stable kernel-2.6 and probably few commits per year).

Finally, i agree with you: lustre is the solution...
