        then reset it this way i remove it from cluster and restart the

      <div>now rabbit@CHETANDEV starts and works fine but when i try to

      <div>i think it is trying to cluster with rabbit@CHETANDEV but

                &gt;<br>
                &gt;&gt;&gt; i clustered them as given on rabbitmq

                &gt;&gt;&gt; on the first place both nodes are running<br>
                &gt;&gt;&gt; now i stopped app using rabbitmqctl

                &gt;&gt;&gt; i clusterd that node with another using

                showing fine then i did as i<br>
                &gt;&gt;&gt; mentioned earlier<br>
                &gt;<br>
                &gt; That will make rabbit@CHETANDEV a *ram* node. To
                make both nodes disk nodes the node itself would have to
                be mentioned in the cluster command too, i.e.
                'rabbitmqctl cluster rabbit@SHIKHAR rabbit@CHETANDEV'.<br>
                &gt;<br>
                &gt;&gt;&gt; &nbsp; &nbsp;2. now i stop node rabbit@SHIKHARM using
                &nbsp;rabbitmqctl stop commnad<br>
                &gt;&gt;&gt; &nbsp; &nbsp;3. now i start the node rabbit@SHIKHARM
                using rabbitmq-server<br>
                &gt;&gt;&gt; &nbsp; &nbsp;start commnad<br>
                &gt;<br>
                &gt; You have just stopped and restarted the clusters'
                only disk node. Rabbit clusters won't function properly
                if they have only ram nodes.<br>
                &gt;<br>
                &gt;&gt;&gt; &nbsp; &nbsp;4. and then i check cluster status it
                shows only one running node<br>
                &gt;&gt;&gt; &nbsp; &nbsp;Cluster status of node rabbit@CHETANDEV

                &gt;&gt;&gt; &nbsp; &nbsp;...done.<br>
                &gt;<br>
                &gt; Try running that command against rabbit@SHIKHARM. I
                suspect it will tell you that it only knows about
                itself.<br>
                &gt;<br>
                &gt; Anyway, I suggest you change your cluster
                configuration s.t. both nodes are disk nodes.<br>
