This answer I've been waiting, but please do not get me wrong, I'm thankful for that.
Of course I'm a beginner in this topic, because of that I try to carry Information about it.
I'm aware that there is no general statement to give, when I asked "how to build a cluster".
It don't have to be a cluster for thousands of people with just more than 500 nodes, just for institut (15 - 20 user). But before it can be built, used .... Someone have to inform. And this is my part. I'm searching for sources to inform, unfortunately there are less sources, respectively I don't find them.
My intention is to begin at point zero of the hpc-topic and then to make gradually steps to the wright direction. For that I have hardware to test to build a "little" cluster to get first experience.
The goal of the entire project is to decide, whether to built the needed cluster on my own. As always, the point is to save costs.

-h Print this help, then exit
-V Print program version information, then exit
-v Produce verbose output

-f configfile
Validate an alternate config file without preloading it with default values.

DEFAULT
Default operation for ccs_config_validate is to load the currently configured environment and verify the outcoming configuration.
Example 1: current environment uses a configuration file (/etc/cluster/cluster.conf).
The user modifies cluser.conf and executes ccs_config_validate without options. The tool will validate the modified cluster.conf
after including default values.
Example 2: current environment is set to load the configuration from LDAP. Users
modifies LDAP databse and before pushing the change to the nodes, she/he can issue ccs_config_validate to verify the contents o the
LDAP database automatically (as long as the correct LDAP environment is set in the cman/cluster sysconfig/defaults files).
