      Linux 2.6.32-29-server #58-Ubuntu SMP Fri Feb 11 21:06:51 UTC 2011 x86_64 GNU/Linux, Solr snapshot from 29th of February 2012, 2 Solr machines with 1 slice each and 0 replica

      Description

      Scenario: ensure that data is replicated when empty replica slices become leader slices
      Given a SolrCloud cluster is running with
      number of servers (Solr nodes): 2
      number of slices per node: 1
      number of replica per slice: 0
      number of documents in leader slice on first Solr node: 4
      number of documents in leader slice on second Solr node: 1
      When I configure each node with 1 replica per slice
      And I stop all nodes
      And I start the nodes one at a time
      Then I would expect that the SolrCloud cluster is running with
      number of servers (Solr nodes): 2
      number of slices per node: 1
      number of replica per slice: 1
      number of documents in leader slice on first Solr node: 4
      number of documents in replica slice on second Solr node: 4
      number of documents in leader slice on first Solr node: 1
      number of documents in replica slice on second Solr node: 1

      Testresult: data is not replicated
      number of servers (Solr nodes): 2
      number of slices per node: 1
      number of replica per slice: 1
      number of documents in leader slice on first Solr node: 4
      number of documents in replica slice on second Solr node: 0
      number of documents in leader slice on first Solr node: 0
      number of documents in replica slice on second Solr node: 1

      When the first Solr node is started the added replica slices are declared leaders
      When the second Solr node is started the slices which were previously leaders are declared replica
      And the data is not replicated from the leader slices to the replica slices or vice versa
      ==> data is not replicated
