Hi all,
I've managed to pass the other problem. after installing FC5 I updated
everything (with 'yum update') and it was under that configuration that
the installation script was unable to determine the machine's architecture.
I've fresh installed FC5 (1 headnode + 1 client) and everything went
smooth. I got to the test phase and every test passed BUT Ganglia!!! In
the ganglia.err file (pasted below) the client (molevol1.ub.edu) looks
OK and so the problem seems to be with the headnode (molevol.ub.edu)
that does not show up in CLUSTER HOSTS. Since it is a small cluster I've
also set the headnode to an execution host (could this be the problem?).
I've also checked for gmond and it is running in all machines.
thanks in adv,
FG

The number of nodes expected is different from the number of nodes detected.
Check to see if gmond is running on all your nodes and make sure that you
are not having any network issues.
