[PATCH]: Inconsistent recmaster during election.

[Kenny Dinh]

Hello,

I have a cluster with 2 CTDB nodes.  My test does the following:

* Restart ctdb service on RecMaster node (Node 1).
* Restart ctdb service on NonRecMaster node (Node 0).
* When ctdb service on NonRecMaster(0) is started, it triggered an election.
* During the election process, NonRecMaster(0) node responded to
"CTDB_CONTROL_GET_RECMASTER" from RecMaster(1) with Node 1 as the
recmaster.  However, when processing the election message, NonRecMaster(0)
node indicated that it won the election.  The inconsistency caused the
RecMaster(1) to trigger new election.  The cycle is repeated 4 times until
RecMaster(1) decided to ban the culprit( Node 0).

Attached are the ctdb log from RecMaster and NonRecMaster, and a proposed
patch.  Essentially, NonRecMaster should not win the election if it
responded that a different node is the recovery master.

Please verify if my patch is correct.

Thanks,
Kenny
