Creating Replicas of Existing Shards
You can create additional replicas of existing shards using a command of the following
form:
solrctl core --create <newCore> -p collection=<name> \
-p shard=<shard_to_replicate>For example, to create a new replica of the collection named
collection1 that is comprised of shard1, use the
following command:
solrctl core --create collection1_shard1_replica2 \
-p collection=collection1 -p shard=shard1
