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: Dan Berindei
Priority: Critical
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.
