Description of problem: Traceback (most recent call last): File "/usr/sbin/system-config-cluster", line 370, in change_lockserver self.model_builder.switch_lockservers() File "/usr/share/system-config-cluster/ModelBuilder.py", line 532, in switch_lockservers self.cluster_ptr.removeChild(self.CMAN_ptr) File "/usr/share/system-config-cluster/TagObject.py", line 17, in removeChild self.children.remove(child) ValueError: list.remove(x): x not in list Version-Release number of selected component (if applicable): [root@tank-03 ~]# rpm -qa | grep system-config-cluster system-config-cluster-0.9.30-1.0
This error was caused as part of another action: Creating a DLM cluster from scratch and then converting it. The code that creates a new DLM cluster was not saving a pointer to the cman object. This is fixed now in 0.9.31-1.0
fix verified.
