PartitionHandling: consider less than numOwners partitions ---------------------------------------------------------- Key: ISPN-4574 URL: https://issues.jboss.org/browse/ISPN-4574 Project: Infinispan Issue Type: Bug Components: Core Reporter: Mircea Markus Assignee: Dan Berindei Priority: Critical Labels: partition_handling Fix For: 7.0.0.Beta2 If the following two conditions are simultaneously met during a split brain: a) less than numOwners nodes leave b) two clusters are formed having that size Then both partitions would be considered as available. E.g. a cluster of 6 nodes with numOwners=4, with a split brain resulting in 3 and 3 nodes partitions. We should add some logic to prevent this situation, e.g. by requiring the remaining partition to have at least numOwners members.
