Description Chris Feist 2010-06-14 20:33:21 UTC
Description of problem:
Luci only talks to ricci on one node of the cluster, if that node's cluster infrastructure is stopped (service cman stop), luci will continue using that node and erroneously report that there is no cluster formed.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Create/Add a 2 node cluster 
2. Stop ricci on first node
3. Hit refresh in the luci interface 3 times
4. start ricci on the first node
5. Run 'service cman stop' on the second node
6. Refresh the luci interface 3 times, both nodes will appear to be not members of the cluster.
7. Login to the 1st node and run 'cman_tool status', you will see that the cluster is still in fact running and that the 1st node is a member of the cluster.

Actual results:
Cluster appears to be down from luci interface

Expected results:
Luci should show that the cluster is working but the second node is not part of the cluster
