[Linux-HA] One-way failover?

[Alexey Zilber]

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
