Francesco Nigro updated ARTEMIS-3345:
-------------------------------------
Description:
A failing-back master forget its Node ID and on broker restart, having a
different Node ID it can become live, without checking for any existing live
with its old Node ID.
This is happen because of this mechanics from SharedNothingBackupActivation:
# {{SharedNothingBackupActivation::init}} is going to call
activeMQServer.resetNodeManager that's re-creating a NodeManager with
replicatingBackup == true
# SharedNothingBackupActivation::run is then
{code:java}
// move all data away:
activeMQServer.getNodeManager().stop();
activeMQServer.moveServerData(replicaPolicy.getMaxSavedReplicatedJournalsSize());
activeMQServer.getNodeManager().start();
{code}
was:
A failing-back master forget its Node ID if any error happen on failover and
restart as an empty backup.
On broker restart, it got a different NodeID and become live.
> Shared-Nothing Replication Master loose its Node ID on failed fail-back
