----------------------------------

             Summary: Replicated cache with numOwners=1 doesn't send writes to backups
                 Key: ISPN-7553
                 URL: https://issues.jboss.org/browse/ISPN-7553
             Project: Infinispan
          Issue Type: Bug
          Components: Core
    Affects Versions: 9.0.0.CR2
            Reporter: Dan Berindei
            Assignee: Dan Berindei
            Priority: Critical
             Fix For: 9.0.0.Final


{{BaseDistributionInterceptor.primaryReturnHandler()}} doesn't replicate writes to the backups if {{cacheConfiguration.clustering().hash().numOwners() == 1}}. That check is incorrect, because a segment can have more owners than configured:

1. In a replicated cache, the configured {{numOwners}} is ignored, and all the members are owners.
1. Even in a distributed cache, during rebalance, the segments being moved will have more than {{numOwners}} owners.
