We are trying to enable our product on RHOS 10/12/13. Since corosync with multicast mode fails to form cluster. We learnt from experiments that it only works if the single compute node is used(when all nodes are on same underlying hardware box). Anyone has any inputs/suggestions on how to go forward or any tips around the same? Sometimes we get such continuous streams of retransmission:

Feb 14 08:54:27 corosync [TOTEM ] Retransmit List: a 10 Feb 14 08:54:27 corosync [TOTEM ] Retransmit List: a 10 Feb 14 08:54:27 corosync [TOTEM ] Retransmit List: a 10 Feb 14 08:54:27 corosync [TOTEM ] Retransmit List: a 10 Feb 14 08:54:27 corosync [TOTEM ] Retransmit List: a 10 Feb 14 08:54:27 corosync [TOTEM ] Retransmit List: a 10
