[jboss-jira] [JBoss JIRA] (JGRP-1910) MERGE3: Do not lose any members from view during a series of merges

MERGE3: Do not lose any members from view during a series of merges ------------------------------------------------------------------- Key: JGRP-1910 URL: https://issues.jboss.org/browse/JGRP-1910 Project: JGroups Issue Type: Bug Reporter: Radim Vansa Assignee: Bela Ban Fix For: 3.6.3 Attachments: SplitMergeTest.java When connection between nodes is re-established, MERGE3 should merge the cluster together. This often does not involve a single MergeView but a series of such events. The problematic property of this protocol is that some of those views can lack certain members, though these are reachable. This causes problem in Infinispan since the cache cannot be fully rebalanced before another merge arrives, and all owners of certain segment can be gradually removed (and added again) to the view, while this is not detected as partition but crashed nodes -> losing all owners means data loss. Removing members from view should be the role of FDx protocols, not MERGEx.
