Hi Eddie,

thanks a lot for your promt reply.
Yesterday I finally managed to set up my nodes.

Maybe it is not a bad idea to edit the documentation a bit, so that it is
explicitely written, that DUCC has to be installed once on one node, and
then
the installation directory has to be mounted on the same spot on all the
other
nodes.
Maybe it will save someone like me a couple of hours.

Thanks again and cheers,
Sergii
