bq: Shouldn't this: &node=x.x.x.x:9001_solr <http://x.x.x.x:8984/solr/admin/collections?action=ADDREPLICA&collection=test2&shard=shard1&node=x.x.x.x:9001_solr>
Actually be this? &node=x.x.x.x:9001/solr <http://x.x.x.x:8984/solr/admin/collections?action=ADDREPLICA&collection=test2&shard=shard1&node=x.x.x.x:9001_solr> (Note the / instead of _ ) Good thing you added the note, 'cause I was having trouble seeing the difference. No. The underscore is correct. The "node" in this case is the name registered in Zookeeper in the "live nodes" znode, _not_ a URL or whatever... As to your two methods of moving a shard around. Either one is fine, although the first one (copying the directory and "doing the right thing" to edit core.properties) is a little dicier in that you're doing hand edits. Personally I prefer the ADDREPLICA solution. In fact I've moved replicas around by ADDREPLICA, wait, DELETEREPLICA...
