Re: Re-create shard with compositeId router and known hash range

Yes, Solr will pick that up. You won't have any replicas though so you'll have to ADDREPLICA afterwards. You could use the EMPTY option on the creteNodeSet of the Collections API to create a dummy collection to see what a no-replica shard should look like as a model Best, Erick On Mon, Jun 13,

Well, how brave do you want to be ;)? There's no great magic to the Zookeeper nodes here. If you do everything just right you could create one manually. By that I mean you could "hand edit" the znode with the Zookeeper commands, you'd have to dig for the exact commands You _may_ be able to use

Re-create shard with compositeId router and known hash range

Hi. We have a SolrCloud setup with 20 shards, each with only 1 replica, served on 8 servers. After a server went down we are left with 16 shards, which means that some of the compositeId hash ranges aren't hosted by any cores. Somehow the shards/cores didn't come back after the server came up
