You can delete replicas from shard by using this command /admin/collections?action=DELETEREPLICA&collection=collection&shard=shard&replica=replica
Delete a replica from a given collection and shard. If the corresponding core is up and running the core is unloaded and the entry is removed from the clusterstate. If the node/core is down , the entry is taken off the clusterstate and if the core comes up later it is automatically unregistered. <http://lucene.472066.n3.nabble.com/file/n4164943/Screen_Shot_2014-10-20_at_3.png> Example : http://10.0.1.6:8983/solr/admin/collections?action=DELETEREPLICA&collection=test2&shard=shard2&replica=core_node3 -- View this message in context: http://lucene.472066.n3.nabble.com/Solr-replicas-stop-replication-and-start-again-tp4164931p4164943.html Sent from the Solr - User mailing list archive at Nabble.com.
