I have two nodes named powerone and powertwo. Is it necessary to add them in
/etc/hosts file?
Since I have the cluster up and running, it means that the nodes are
communicating with each other. I am able to ping between the two nodes.
It is the drbd which is not able to connect. I also ran ethereal and found
that there is no communication request on the specified port(7788)
whatsoever. Why it is not binding with the network card I do not know.

I am sending my drbd.conf file again.

Thanks for your help
