Could you please try with shorter sentences, I got lost half way. Apart from
that, please upgrade from 2.1.3 to pacemaker.  2.1.3 is old and you won't
get much support for it.

Actually I am already spent lot of time with 2.1.3 and  Pacemaker is totally
new 4 me and I have done load of R & D on 3 node clustering with 2.1.3
version. And also my management wants me to live this setup as soon as
possible. So I am just wondering for any help on 2.1.3 version.

My 3 node cluster is working fine if I test the cluster by getting down my
active nodes one by one.

But this issue come when my both Active machine gets down simultaneously one
after another.

Problem is:

In case of node_master active node fails and failover its resources to
node_slave passive node (Problematic scenario):-
If node_master fail there resources on node_slave then there isn't any
problem for that but at the same time if node3 fail there resources then
node_master resources stops on node_slave and node3 resources starts over
node_slave node.

But whereas,

In case of node3 active node fails and failover its resources to node_slave
passive node (No problem with this scenario):-
If node3 fail there resources on node_slave then there isn't any problem and
at the same time if node_master fail there resources on node_slave then
node3 finds that node_slave already have occupied with resources and stop
node3 resources. (Perfect scenario)

Any help will be greatly appreciated!

Thanks,
