[jboss-jira] [JBoss JIRA] Commented: (JBMESSAGING-1173) Merge after lost of network connectivity between cluster members (handle the split-brain situation)

Tim Fox commented on JBMESSAGING-1173:
--------------------------------------
For JBM 2.0 we can allow to specify a quorum size in the cluster config.
When a connection fails over, the node will try to contact up to quorum number of members
- if it succeeds then it will assume responsibility as live, otherwise it will doom itself
as a network partition occurred.
Merge after lost of network connectivity between cluster members
(handle the split-brain situation)
---------------------------------------------------------------------------------------------------
Key: JBMESSAGING-1173
URL: https://jira.jboss.org/jira/browse/JBMESSAGING-1173
Project: JBoss Messaging
Issue Type: Feature Request
Components: JMS Clustering
Affects Versions: 1.4.0.SP2
Environment: Any clustered
Reporter: Mike Clark
Assignee: Tim Fox
Fix For: 2.0.0 Beta
JBM does not currently support the merging of cluster segments that have gotten into the
"split-brain" situation. This occurs when network connectivity is lost between
subsets of a cluster. Each subset assumes the other is gone and acts appropriately. When
the network connectivity is restored, they do not merge back into a single cluster but
remain as independent clusters (the spit-brain).
This feature request is to add cluster merging to prevent the split-brain situation.
