Hi all,

Suppose i have 2 nodes running heartbeat v2, and 1 resource. Lets say, for some reason, the resource that runs in node A fails. Then resource fails-over at node B. Then, the resource fails again. In ths situation, the resource can't failback to node A. It only fails- back when i cleanup the resource from the LRM ( crm_resource -C -r myresource -H nodeA )

crm_verify -LV  says:

crm_verify[..]...: WARN: unpack_rsc_op: Processing failed op (myservice_start_0) for myservice on nodeA

crm_verify[..]...: WARN: unpack_rsc_op: Handling failed start for myservice on nodeA

crm_verify[..]...: WARN: unpack_rsc_op: Processing failed op (myservice_start_0) for myservice on nodeB

crm_verify[..]...: WARN: unpack_rsc_op: Handling failed start for myservice on nodeB


I found in http://www.linux-ha.org this about auto_failback: *NOTE*: auto_failback does not have any effect on a Release 2 CRM- style cluster (one configure with crm_on). For CRM-style clusters, this has been replaced with the <http://www.linux-ha.org/v2/dtd1.0/annotated#default_resource_stickiness >default_resource_stickiness attribute in the CIB.

How is default_resource_stickiness attribute used and work?

Is there any way to make HA to auto cleanup a resource of the LRM?

In pacemaker 0.7 you can now time-out failed actions




Thanks!

Ioannis.
