If I am not mistaken the only way to create a new shard from a collection in 4.4.0 was to use cores API. That worked fine for me until I used *other* cores API commands. Those usually produced null ranges.
In 4.5.0 this is fixed with newly added commands "createshard" etc. to the collections API, right?

Chris, can you post your complete clusterstate.json? Do all shards have a null range? Also, did you issue any core admin CREATE commands apart from the create collection api. Primoz, I was able to reproduce this but by doing an illegal operation. Suppose I create a collection with numShards=5 and then I issue a core admin create command such as: http://localhost:8983/solr/admin/cores?action=CREATE&name=xyz&collection=mycollection51&shard=shard6 Then a "shard6" is added to the collection with a null range. This is a bug because we should never allow such a core admin create to succeed anyway. I'll open an issue.
