[Linux-cluster] Netmask of IP Address resource system-config-cluster 1.0.25




Hi,
I'm a bit baffled, that I can't enter a netmask when configuring an IP Adress as a ressorce with the the system-config-cluster 1.0.25 tool.
As a result, when starting rgmanager, the Service IP Adress gets a /32 netmask, which is not correct of cause.

Since there won't be too many changes to the cluster.conf file in the long run, it would be alright to just edit it by hand. Unfortuneatly I wasn't able to figure out what the correct syntax is

eg.

<ip address="10.112.24.17/24" monitor_link="1"/>

or

<netmask = "255.255.255.0"/>

Is the DTD of cluster.conf generally available?

My cluster.conf is attached below. Please feel free to suggest improvements, since I'm totally new to the RH ClusterSuite.
For example, I don't want to use a fencing device, because I don't need any shared storage for the MySQL Cluster, which works with two seperate data nodes, that is the data itself will exist twice physically on seperate storage.

Do I have to configure some kind of fencing anyways. If yes, how would this kind of dummy fencing look like in the cluster.conf?
(Or is the <fencedevices/> entry all I need?)

Many thanks in advance !
