RHEL cluster issue on two node - Urgent

Hi ,

I am building a two node cluster (each node with rhel 5.3 64 bit with cluster suit). But I could see the qdisk coming offline after cman starts. I am attaching the cluster.conf file here with. Please do let me know if there is any issue especially on voting procedure.

Hi

I think the problem could be related to the amount of score of your heuristic script.
The score of the heuristic script should be at least the amount of minimum score of your quorum. Otherwise quorum doesn't work.

Re: RHEL cluster issue on two node - Urgent

Kisseleff is right: you have only one heuristic for quorumd, giving a score of 1 point. With that, quorumd will never reach the min_score of 3, so it will never cast its 3 quorum votes.

Recommendation: either set min_score to 1, or increase the score value of your ping heuristic to 3.

I also see your cman tag is empty. As your total number of votes is 5, I would have expected to see:



instead of just "". But fix the quorumd score problem first: once this cman line is in place, your cluster won't ever achieve quorum without the votes given by quorumd.

(When a two-node cluster is using quorumd, there is no need for special two-node mode, so you should set 'two_node="0"'.)
