Add a new shard in collection

["Gell-Holleron, Daniel" <da...@gb.unisys.com>]

Hi there,

Hoping you can help.

If I want to add a new shard (on a new solr server) to an existing collection. What would be the best way to be able to balance all the data again, so it is balanced across all shards?

With reindexing, I guess this will take additional disk space whilst the reindex takes place, before clearing it once the reindex has completed?

Or is Solr clever enough to distribute updates to the new shard that has a lot less data?

We are currently using Solr 8.9.0.

Thanks,

Daniel
