----------------------------------------
Summary: Backup forget coordination-id after quorum loss
Key: ARTEMIS-3429
URL: https://issues.apache.org/jira/browse/ARTEMIS-3429
Project: ActiveMQ Artemis
Issue Type: Bug
Affects Versions: 2.18.0
Reporter: Francesco Nigro
Assignee: Francesco Nigro
Assuming a multi-primary set-up, if the broker acting as backup lost quorum, is
restarted without applying the coordination-id patching on NodeManager: if its
local activation sequence is > 0 (because of a past sync with the other live)
the backup succeed to activate, causing a split-brain (although its NodeID is a
random one vs the original coordination-id).
