[Linux-HA] RE: One-way failover?

[Luettgen, John (N-ENSCO)]

Alex, not configurable, but still possible.  Simply having the node "a" not start HA, if the other node has the services running.  Not complicated to do, just a bit of logic to consult the other node to check it state and service.

OK, John

Hi All,

  Is it possible to do a one-way failover with Heartbeat?  Here's the
scenario.  We are running mysql on node a and the slave on node b.  We want
to failover one way, ie. node a fails, node b takes over.  If node b fails,
regardless if node a is up or not, we don't want any services coming back
up.  This will allow us to move data back to the master (node a) and bring
it up manually.

Is this scenario possible?

Thanks!
Alex
