For what it's worth, I have had a similar problem, with our central
networking
department telling me that "it should work". I have had a single node
unable to
join the 3-node cluster I'm currently trying to get working. All
physical machines,
no VMs.
Solution: Hook them all up on the same switch, no more problems with
that part...

Hi..
I have tried both multicast and broadcast to no avail, as above I am
moving the systems to the same ESX to try and rule out the networking
end of things, I have not tried the tcpdump but was running wireshark
in an attempt to do the same as you recommended

Hi all
I am having no end of trouble getting a basic Active Active Cluster
working. at the moment it is in test / proof of concept and has manual
fencing in place but I cannot for the life of me get the 2 nodes to
join to the one cluster (they both report joined in crm_tool status
but only to a local clustered instance if that makes any sence)
I have tried to use luci and system-config-cluster to get this up and
running and have been at it over a week, the network guys swear that
there is nothing blocking multicast traffic between them and the
firewalls have been disabled (they are on the same VLAN but connected
to different switches) servers have been rebuilt and have RHEL 5.5
installed
your problem is the multicast traffic - check with tcpdump if it is
comming to the other server at all (network) and if it is, then doublecheck
the firewall.
alternatively you may try using broadcast instead of multicast
Shared Storage is being provided by an Active Active DRBD setup
(tested and working)
I have attached a copy of my cluster.conf
Thanks in advance
