    Problem with capacityFactor=0 and restart of all nodes with capacityFactor > 0

      Hi,

      here is my scenario.

       

      I have a only one DIST_SYNC cache, most of the JVM in the cluster are configured with capacityFactor = 0 (like the distibutedlocalstorage=false property of Coherence) and some node are configured with capacityFactor>0 (for instance 1000). We are talking about 100 nodes with capacityFactor=0 and 4 nodes of the other kind, al the cluster is indide one single "site/rack". Partition Handling is off, numOwners is 1.

      When all the nodes with capacityFactor > 0 are down the cluster comes to a degraded state from which it cannot recover anymore without a full cluster restart.

      If I enable partition-handling AvailablyExceptions start to be throw and I think is the expected behaviour  (Infinispan User Guide).

       

      I think this is the problem and it is a bug:

      This is the actual configuration:

       

      GlobalConfiguration globalConfig = new GlobalConfigurationBuilder()

      .globalJmxStatistics()

      .allowDuplicateDomains(true)

      .cacheManagerName(instanceName)

      .transport()

      .defaultTransport()

      .clusterName(clustername)

      .addProperty("configurationFile", configurationFile)   (udp for my cluster, approx 100 machines)

      .machineId(instanceName)

      .siteId("site1")

      .rackId("rack1")

      .nodeName(serviceName + "@" + instanceName)

      .remoteCommandThreadPool().threadPoolFactory(CachedThreadPoolExecutorFactory.create())

                      .build();

       

              Configuration wildcard = new ConfigurationBuilder()

      .locking().lockAcquisitionTimeout(lockAcquisitionTimeout)

      .concurrencyLevel(10000).isolationLevel(IsolationLevel.READ_COMMITTED).useLockStriping(true)

                      .clustering()

      .cacheMode(CacheMode.DIST_SYNC)

      .l1().lifespan(l1ttl)

      .hash().numOwners(numOwners).capacityFactor(capacityFactor)

      .partitionHandling().enabled(false)

                      .stateTransfer().awaitInitialTransfer(false).timeout(initialTransferTimeout).fetchInMemoryState(false)

      .storeAsBinary().enabled(true).storeKeysAsBinary(false).storeValuesAsBinary(true)

      .jmxStatistics().enable()

                      .unsafe().unreliableReturnValues(true)

      .build();

       

      Should I report a bug in JIRA ?

       

      One workaround is to set capacityFactor = 1 instead of 0, but I do not want "simple-nodes" (with less RAM) to becaome key-owners

      For me this is a shostopper problem
