             Summary: PartitionHandling: consider less than numOwners partitions
                 Key: ISPN-4574
                 URL: https://issues.jboss.org/browse/ISPN-4574
             Project: Infinispan
          Issue Type: Bug
      Security Level: Public (Everyone can see)
            Reporter: Mircea Markus
            Assignee: Mircea Markus


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.
