[ClusterLabs] corosync not able to form cluster

[Prasad Nagaraj]

Hi Christine - Thanks for looking into the logs.
I also see that the node eventually comes out of GATHER state here:

Jun 07 16:56:10 corosync [TOTEM ] entering GATHER state from 0.
Jun 07 16:56:10 corosync [TOTEM ] Creating commit token because I am the rep.

Does it mean, it has timed out or given up and then came out ?

second point, I did see some unexpected entries when I did tcpdump on the
node coro.4.. [ Its also pasted in one of the earlier threads] You can see
that it was receiving messages like

10:23:17.117347 IP 172.22.0.13.50468 > 172.22.0.4.netsupport: UDP, length
332
10:23:17.140960 IP 172.22.0.8.50438 > 172.22.0.4.netsupport: UDP, length 82
10:23:17.141319 IP 172.22.0.6.38535 > 172.22.0.4.netsupport: UDP, length 156

Please note that 172.22.0.8 and 172.22.0.6 are not part of my group and I
was wondering why these messages are coming ?

Thanks!
