That's why you're having trouble. Half the index disappeared when you deleted that shard, along with the information telling SolrCloud how to hash documents into that shard. Now it has no information about where to index documents matching the hash range of the deleted shard, so an error is returned when you try. Adding and deleting shards does *NOT* change document distribution. There are only two ways to change how documents are hashed among your shards: Either you can split a shard, making new ones where each has a portion of the hash range of the original, or you can create an entirely new collection. To get out of the hole you're in now, either build a new collection with the actual shard count that you want so it's correctly set up, or edit the clusterstate in zookeeper to change the hash range (change 80000000 to 00000000) and then restart all your solr servers. For the latter option, a complete reindex is also a good idea. If you build a new collection, you can delete the old one and then set up a collection alias so that the original name works with the new collection. A reindex will be required, because the new collection will initially have no documents. Thanks, Shawn
