OES11 CRM module cores with "CRM:CRMSetResource: conflicting resource name".

This document (7010731) is provided subject to the disclaimer at the end of this document.

Environment

Novell Open Enterprise Server 11 (OES 11) Linux
Novell Open Enterprise Server 11 (OES 11) Linux Support Pack 1
Novell Cluster Services 1.8.4

Situation

This problem was found after creating a number of cluster resources and specifying a wrong name.

In an attempt to correct that, after deleting the resource, and re-creating the same cluster resource using a proper name (but using the same cluster resource IP address) we observed all cluster nodes, other than the node running the Master_IP_Address resource, to be crashing in the kernel panic listed below.

After enabling CRM debugging (uncomment the line that reads  "# echo -n "TRACE CRM ON" > /proc/ncs/cluster" in file  '/opt/novell/ncs/bin/ldncs') and restarting Novell Cluster Services on all the nodes in the cluster, and repeating the test, the following kernel panic was observed :

"Kernel panic - not syncing: NWCLSTR_Abend: CRM:CRMSetResource: conflicting resource name"

Excerpt from the core log file :

Resolution

The problem has been identified in the Novell Cluster Services modules.

A solution is currently scheduled to be released in a future support pack.
