Hi Isabelle, If I understood correctly your question, you can check shard distribution status at admin page http://localhost:8983/solr/#/~cloud
if you started solr by using command like $ java -Djetty.port=7574 -DzkHost=localhost:9983 -jar start.jar ( https://cwiki.apache.org/confluence/display/solr/Getting+Started+with+SolrCloud ) then the nodes are assigned with the order 1-shard leader -> 2-shard leader -> 1-shard replica -> 2-shard replica of course, form the second time, the node’s status does not change.
