I would refrain from sharding until you really need it (roughly: index size much larger than RAM, very high update rate etc.), so keep shards=1 and replication factor=3 for your 3 node cluster. To examine the behaviour you have experienced (node not coming up), we'd need the exact steps and log output. Kind regards Matthias On Tue, Nov 19, 2024 at 10:51 AM Schmidt, Mihael <mschm...@bauformat.de<mailto:mschm...@bauformat.de>> wrote: Hi, I am trying to set up a Solr cluster. I have installed a Zookeeper cluster which works fine. I have set up 3 Solr nodes and created a collection with „number of shards: 3“ and „replication factor: 3“. As far as I understand it every node has every shard and contains a full replication of the whole data. So far so good. I have added some data and done some queries. All worked fine. Now I wanted to test an outage of one node and killed one Solr node. The Solr cluster keeps on functioning. Queries and updates of the index work fine. But when I start the node again it is gets some error message that it could not load the core. I stopped that node again. Deleted all the data in its data home folder and started the node again. Now I don’t get any errors but the node won’t load any data. Under Cloud -> Nodes it says in the column „Replicas“ that all replicas on that node are down. Queries to the restarted node will be successfully answered by that node. In Zookeeper i see that the restarted node is listed under live_nodes and overseer_elect -> leader election. How do I get that node up and running again? I am using Solr 9.6.0 and running Windows 10. Thanks in advance. Mihael Mihael Schmidt Software Engineering Bauformat Küchen GmbH & Co.
