[Pacemaker] spilit brain situation

[Romi Verma]

Thanks for fast reply ,
Ok, Let me explain the situation. i have two nodes cluster . i pulled out
the network cable of one
node which produced spilit brain situation. this time both nodes are
thinking that other one is dead.  each node is thinking itself as DC and on
each node cluster is up and running without quorum.

i am new to openais/pacemaker so dont know much but according to some
documents it seems by default no-quorum-policy is  to "stop" the cluster. i
have not specified any no-quorum-policy that's why i expect that my cluster
should stop if it looses quorum somehow.

But in present spilit brain situation , on each node cluster is up and
running without quorum.   could you please explain why this is happening.

Romi
