    Don&#39;t do that - take the second node out of the cluster whilst the
    other node(s) are still running, so that they can see it leaving.

                &gt;<br>
                &gt; yes, but...<br>
                &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
                rabbitmqctl cluster rabbit@SHIKHARM<br>
                &gt;&gt;&gt; then i started the node using rabbitmqctl
                start_app<br>
                &gt;&gt;&gt; when i checked the cluster status it was
                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.
                &#39;rabbitmqctl cluster rabbit@SHIKHAR rabbit@CHETANDEV&#39;.<br>
                &gt;<br>
                &gt;&gt;&gt;    2. now i stop node rabbit@SHIKHARM using
                 rabbitmqctl stop commnad<br>
                &gt;&gt;&gt;    3. now i start the node rabbit@SHIKHARM
                using rabbitmq-server<br>
                &gt;&gt;&gt;    start commnad<br>
                &gt;<br>
                &gt; You have just stopped and restarted the clusters&#39;
                only disk node. Rabbit clusters won&#39;t function properly
                if they have only ram nodes.<br>
                &gt;<br>
                &gt;&gt;&gt;    4. and then i check cluster status it
                shows only one running node<br>
                &gt;&gt;&gt;    Cluster status of node rabbit@CHETANDEV
                ...<br>
                &gt;&gt;&gt;  
                 [{nodes,[{disc,[rabbit@SHIKHARM]},{ram,[rabbit@CHETANDEV]}]},<br>
                &gt;&gt;&gt;     {running_nodes,[rabbit@CHETANDEV]}]<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>
