[Pacemaker] monitoring attributes

[Giuliano Zorzi]

Hi all,
I'm stuck on something I thought to be very simple, but googling hasn't 
helped me :(

I have a 2 node cluster with an IPaddress2 resource and a 
pacemaker:pingd clone. The resource goes away from the node with pingd 
value = 0 just fine.

Now I need to run a script on the "failed" node when it comes back but I 
can't seem to find a way.

I tried ClusterMon but it seems to work only when the clone resource is 
started/stopped, not when the atrtibute value changes

Is there a way to have this done ?
As last resort I could use a cronjob and monitor the pingd attribute 
with crm_attribute (crm_attribute --query --name=pingd --node node1 
returns "name=pingd value=(null) Error performing operation: cib object 
missing", any idea ?)

Any help will be greatly appreciated

TIA

giuliano
