* Fixed a bug where a stop operation on a server already in shutdown would exit immediately instead of waiting for the server to actually shut off.

* A resource agent receives all configuration information about the resource it manages via environment variables. The names of these environment variables are always the name of the resource parameter, prefixed with OCF_RESKEY_. For example, if the resource has an ip parameter set to 192.168.1.1, then the resource agent will have access to an environment variable OCF_RESKEY_ip holding that value.

When stopping a server;
14:03 < lge> "on-fail: block"
14:03 < lge> is per operation type.
14:08 < lge> anyways, you can also "on-fail: retry"
OK, set the stop timeout to 60, set 'on-fail: block" and set the failure-timeout to 60 and see how pacemaker reacts.

Migrate servers;
- Let ScanCore set 'node-health' attribute (http://clusterlabs.org/pacemaker/doc/en-US/Pacemaker/1.1/html-single/Pacemaker_Explained/index.html#s-node-health)
- Set 'migration-limit' to '1' to enforce serial live migration (http://clusterlabs.org/pacemaker/doc/en-US/Pacemaker/1.1/html-single/Pacemaker_Explained/index.html#s-cluster-options).
Migrate a single server by setting a location constraint against the node we want the VM off of.
