First, thank you very much for your very long answer !
It helps a lot, I was quite lost...

That is the problem : setting up the cache with venus-setup <host> 30000
allows me to access normally to the files (I could not even read my big tar
file - not so big : 11M). I had this ENOSPACE message even while trying to read
which was very frustrating...
All right now it is working with such a configuration... But isn't 30M rather
big just for a cache ? Is there a way to use less memory on the clients to save
some memory for the others apps without having to swap ?
I guess I will try to have an other look to the venus manual...
