Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

We have given the following setting with corosync and pacemaker.

crm configure rsc_defaults resource-stickiness="100"

And it works fine when the primary server goes down. But it wont work revers, resource(httpd) migration back to primary after restarting the primary and bringing down the secondary.

ie

As I said everything works well, but i need just one thing, i have the directive " resource-stickiness="100", when node1 is down, the node2 starts all resources and prevent failback again though the node1 is up, back i need move all resources to the first one when I certainly sure the node1 is runnig, is there some directive to tell pacemaker that move back again the to node1 automatically? i mean, is posibble to move back resources to node1 when It has passed certain time, maybe 1 hour or something?

Instead of setting the stickiness to 100, make it INFINITY and try this command

crm configure rsc_defaults resource-stickiness="INFINITY"

Make the stickiness INFINITY and try. Also create a new key on the secondary server which allow with that key to log in to primary server.
