Hi, I have the following situation using SolrCloud:
deleteCollection "foo" -> "Could not find collection:foo" createCollection "foo" -> "Error CREATEing SolrCore 'foo_shard1_replica1': Could not create a new core in solr/foo_shard1_replica1/as another core is already defined there" unload Core"foo_shard1_replica1", delete index, delete dir -> No such core exists 'foo_shard1_replica1' My clusterstate.json is empty: get /clusterstate.json {} However, the /solr directory of my server does have the directory "foo_shard1_replica1" How can I delete this phantom core / collection without manually deleting the directory and restarting my servers? Thanks!
