[ClusterLabs] Peer (slave) node deleting master's transient_attributes

[Stuart Massey]

Can someone help me with this?
Background:

"node01" is failing, and has been placed in "maintenance" mode. It
occasionally loses connectivity.

"node02" is able to run our resources

Consider the following messages from pacemaker.log on "node02", just after
"node01" has rejoined the cluster (per "node02"):

Jan 28 14:48:03 [21933] node02.example.com        cib:     info:
cib_perform_op:       --
/cib/status/node_state[@id='2']/transient_attributes[@id='2']
Jan 28 14:48:03 [21933] node02.example.com        cib:     info:
cib_perform_op:       +  /cib:  @num_updates=309
Jan 28 14:48:03 [21933] node02.example.com        cib:     info:
cib_process_request:  Completed cib_delete operation for section
//node_state[@uname='node02.example.com']/transient_attributes: OK (rc=0,
origin=node01.example.com/crmd/3784, version=0.94.309)
Jan 28 14:48:04 [21938] node02.example.com       crmd:     info:
abort_transition_graph:       Transition aborted by deletion of

Jan 28 14:48:05 [21937] node02.example.com    pengine:     info:
master_color: ms_drbd_ourApp: Promoted 0 instances of a possible 1 to master

The implication, it seems to me, is that "node01" has asked "node02" to
delete the transient-attributes for "node02". The transient-attributes
should normally be:
      <transient_attributes id="2">
        <instance_attributes id="status-2">
          <nvpair id="status-2-master-drbd_ourApp"
name="master-drbd_ourApp" value="10000"/>
          <nvpair id="status-2-pingd" name="pingd" value="100"/>
        </instance_attributes>
      </transient_attributes>

These attributes are necessary for "node02" to be Master/Primary, correct?

Why might this be happening and how do we prevent it?
