Re: system-config-cluster error

I am configuring a cluster of 2 HP machines and I just installed Fedora Core 4 on both machines with the proper services to run a cluster and share resources. I managed to share a disk array as a single partition with both machine by the Global File System.

To further configure the cluster I installed the system-config-cluster RPM package as suggested by the documentation which anyway is not part of the Fedora Core 4 CDs. I found it on rpmfind and installed with an rpm -i command. I can start the application and make changes but if I try to save them I get the following trace.

[root AICLSRV01 cluster]# Traceback (most recent call last):

Anybody can help me to make it work? Or perhaps should I get a different package? The one I downloaded is system-config-cluster-1.0.24-1.0.noarch.rpm. Thanks in advance.

system-config-cluster-1.0.24-1.0 is the version that the development repository carries.. The version seems to require the below.

You might try to remove the version that you have installed and temporarily activating the fedora-devel-repo and using yum to install system-config-cluster and matching versions below. If s-c-cluster is available for FC4, (I thought that it was, have not checked) yum install the package from the FC4 version to install it. I have not personally worked with the cluster manager to actually create a cluster file system. I was able to save the config file with a few bogus entries without the problem that you describe when saving the changes.

rpm -q --requires system-config-cluster
config(system-config-cluster) = 1.0.24-1.0
python >= 2.3
rhpl >= 0.148.2
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1

Well fix that in the next (upgrade, update, patch release, service pack).
