Hi
Im trying to set up a DRBD/Heartbeat pair using V2
I have a working V1 configuration, where if the active node (nodeA)
is stopped/dies the standby node (nodeB) takes over the DRBD
resources. Then when the stopped/dead node (nodeA) is restarted, the
resources stay on nodeB till manually forced to change over.
I have converted this configuration to V2 and i cannot fully disable
auto failback.
I have set the default_stickiness to INFINITY
no you don't. well you may have in the past, but thats not what the
config below says now.
using -INFINITY tells the cluster to _ALWAYS_ move the resource from
where its running.
to disable auto_failback, set it to INFINITY instead.
and this works fine if i use the standby flag to control the
resource failover.
But if i stop and restart the heartbeat on the active node the
resources failover to the standby node then fail back to the active
node.
It seems Heartbeat remembers where a resource was first run, then
will always try and return it there, even if the default_stickiness
is set.
How can i make Heartbeat V2 to not failback when a resource is re-
started?
