[Linux-cluster] Quorum Disk question

["James Lapthorn" <james lapthorn lapthornconsulting com>]

Good afternoon,

Hopefully somebody can help with a Quorum disk question I have.  I have a
4 node cluster and have adopted a 'last man standing' approach.  Because
of this I use a quorum disk which is I have setup on my SAN.

I have added the following configuration into my cluster.conf file.

<quorumd device="/dev/vpathe" interval="1" tko="10" votes="4">
     <heuristic interval="2" program="ping leoukldb1 -c1 -t1" score="     
    1"/>
     <heuristic interval="2" program="ping leoukldb2 -c1 -t1" score="     
    1"/>
     <heuristic interval="2" program="ping leoukldb3 -c1 -t1" score="     
    1"/>
     <heuristic interval="2" program="ping leoukldb4 -c1 -t1" score="     
    1"/>
</quorumd>

Each node has 1 vote and the quorum disk has 4, therefore Quorum should
remain if 3 nodes are removed from the cluster.

While testing this I have noticed that i get the following error in the log:

 qdiskd[26676]: <notice> Score insufficient for master operation (1/2;
max=4); downgrading

At this point Activity is blocked.

Is this to do with my heuristic programs, should I not ping each memeber
node and maybe ping something like 'localhost'



PLease help
