Hi Ulrich, default value is not set, or null, if you prefer: $ sudo pcs property show --all | grep stickiness default-resource-stickiness: (null) But the error 6 you get from the return code of crm_attribute applies to any other property valued with "null" or whatever value. In this specific case null and zero might count the same. This means that the general (or default) stickiness will make each resource come back on the node it was running on: 1 - RES1 is running on NODE1 2 - NODE1 fails 3 - RES1 move to NODE2 4 - NODE1 resurrect 5 - RES1 go back to NODE1 with a default-resource-stickiness of INFINITY you'll not get step 5, with any other value the cluster will deal with node weights while deciding to move back or not the resource.
