>             Project: Solr
>          Issue Type: Bug
>          Components: replication (java)
>    Affects Versions: 4.0-ALPHA
>         Environment: 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
>            Reporter: Jens Bo Rasmussen
>            Priority: Minor
>              Labels: replica
>             Fix For: 4.8

>   Original Estimate: 96h
>  Remaining Estimate: 96h

> 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
