Subject: Consult the meaning of maxShardsPerNode
Hi,
The following is a part of my cluster status
I configured maxShardsPerNode to 1,but I can still create a collection with 2
shards and 2 replicas each shard on a node(From the web gui).
In addition,if I create a collection with 3 shards and 2 replicas each
shard,the Solr server reports the following error(My Solr cluster has deployed
five Solr instances)
Cannot create collection search4. Value of maxShardsPerNode is 1, and the
number of nodes currently live or live and part of your createNodeSet is 5.
This allows a maximum of 5 to be created. Value of numShards is 3, value of
nrtReplicas is 2, value of tlogReplicas is 0 and value of pullReplicas is 0.
This requires 6 shards to be created (higher than the allowed number)
Now I'm confused about the meaning of maxShardsPerNode.
Thanks.
