      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 replica slices specified in the configuration are added on sequential node restart without loosing data
      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 restart 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: the scenario has been performed several times with success however sometimes data is not replicated; it has been observed that sometimes no data is replicated at all and sometimes only data from one of the slices is replicated
