Hi,
We have upgraded pacemaker version 1.0.12 to 1.1.7
The upgrade was done since resources failed to recover after a timeout 
(monitor|stop[unmanaged]) and logs observed are:

WARN: print_graph: Synapse 6 is pending (priority: 0)
Sep 03 16:55:18 CSS-FU-2 crmd: [25200]: WARN: print_elem: [Action 103]: Pending 
(id: SnmpAgent_monitor_5000, loc: CSS-FU-2, priority: 0)
Sep 03 16:55:18 CSS-FU-2 crmd: [25200]: WARN: print_elem: * [Input 102]: Pending 
(id: SnmpAgent_start_0, loc: CSS-FU-2, priority: 0)
Sep 03 16:55:18 CSS-FU-2 crmd: [25200]: WARN: print_graph: Synapse 7 is pending 
(priority: 0)

Reading through the forum mails, it was inferred that this issue is fixed in 
1.1.7

Platform OS: OEL 5.8
Pacemaker Version: 1.1.7
Corosync version: 1.4.3

Pacemaker and all its dependent packages were built from source 
(tarball:github).
glib version used for build: 2.32.2

The following issue is observed in Pacemaker 1.1.7:
1) There is a two-node cluster.
2) When primary node is rebooted/or pacemaker is restarted, the resources fail-
over to secondary.
3) There are 4 group of services. 
   2 group are not sticky. 
   1 group is master/slave multi-state resource
   1 group is STICKY
4) When primary node comes online, even the sticky resources fail back to 
primary node (Issue)
5) Now, if the secondary node is rebooted, the resources fail over to primary 
node.
6) Once the secondary node is up, only non-sticky resources fail-back. Sticky 
resources remain on primary node.

7) Even if Location preference of sticky resources is set for Node-2(the 
secondary node), still sticky resources fail-back on Node-1.

We're using pacemaker 1.0.12 on Production. We're facing issues of IPaddr and 
other resources monitor operation timing out and pacemaker not recovering from 
it (shared above).

Any help is welcome.

PS: Please mention, if any logs or configuration needs to be shared.

Thanks,
Parshvi
