>             Project: Solr
>          Issue Type: Bug
>          Components: replication (java)
>    Affects Versions: 4.0
>         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: 4.1

>   Original Estimate: 120h

> 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
