Hello All,
I'm starting to really like ZLB -- we've started using it to handle LDAP
traffic to some of our directory servers, and it works great.
For the sake of redundancy, we've been attempting to set up a cluster with
a second machine. All this is using VMware vSphere.
However, they don't seem to be able to communicate over the virtual IP's
that I've set aside for the cluster communication. The clustering action
will succeed, but there will be warnings because the cluster is active on
both machines. The machines do appear to link up and synchronize the
cluster settings, but only one is available via the web interface.
If I try to force a failover by shutting down the machine that I can access
via the web interface, the other does not kick in.
If I start the machine back up, it will cause the control of the cluster to
flap between the two hosts.
I've looked through the archives of this list for solutions, but none of
them have worked so far -- NTP synchronization is fine, rebooting servers
in a specific order doesn't seem to change anything, and I can even ping
one machine from the other while all this madness is going on.
Any thoughts or tips?
