[Linux-cluster] Cluster is failed.

[שלום קלמר]

Hi.

you got some errors on your cluster.conf file.

1. you must check that fence_rsa works berfore starting the cluster.
2. if you are using  quorumd, change cman to : <cman expected_votes="3"
two_node="0"/>
3. put quorumd  votes=1 , min_score=1
4. change your heuristic program to somthing like ping to your router.( its
better to add more heuristics )
5. install most updated rpms of cman openais & rgmanager.
6. clustat should show qdisk is online. cman should start  qdiskd .

for more information you can read :

http://sources.redhat.com/cluster/wiki/FAQ/CMAN  ( it helps me . )


Regards

Shalom.
