I am debugging a Performance problem we are having with our Cluster,
We have a 32 nodes cluster, using a GFS shared Volume,
I would like to know whether this is a good configuration of the
"cluster.conf" File:
[root@genocluster-data symbiose]# more /etc/cluster/cluster.conf
<?xml version="1.0"?>
<cluster config_version="17" name="genouest">
