Hi, We have in lab SolrCloud 5.2.1 2 Shards, each shard has 2 cores/nodes, replication factor is 1. meaning that one node is leader (like old master-slave). (upon collection creation numShards=1 rp=1)
Now there is a problem in the lab, shard 1 has 2 cores, but the number of docs is different, and when adding a document to one of the cores, it will not replicate the data to the other one. If i check cluster state.json it appears fine, it writes there are 2 active cores and only 1 is set as leader. What is the recovery method for a scenario like this ? I dont have logs anymore and cannot reproduce. Is it possible to merge the 2 cores into 1, and then split that core to 2 cores ? Or maybe to enforce sync if possible ? The other shard, Shard 2 is functioning well, the replication works fine, when adding a document to 1 core, it will replicate it to the other. -- - Ilan Schwarts
