I am running NAT LVS. This is used for a compute cluster and so has
permanent connections almost 24/7.
Currently there is not redundancy / failover provision for the director, so
if it dies (for whatever reason) the cluster is out of action. I know that
heartbeat can be used to enable another director if the main director
dies... however, what will happen to the current connections? I assume that
they will be lost as the failover director will not have a list of the
current connections to manage.
Is there anyway that the failover director can keep track of the current
connections so that when it takes over the IP address, the LVS NAT
forwarding can be taken over as well?
I know it's a long shot but I thought it was worth a try.
Steve.
