Hello List!
In the past I did a view installations of Solr5 and Solr6.
So im am uses to install solr
The question is now, I have installed Solr7.4 on 5 Hosts with zookeeper
ensemble (5 Servers).
But I am confused about the replica core numbering:
The naming of the cores are up to core_node10 and the shard replica numbering
also * shard1_replica_n10, on solr5 and solr6 the numbering of the cores was as
high as the solr instances installed.
Eg:
Solr6, 3 Server with zookeeper ensemble
Shard: shard1
• Replica: core_node1
core:WTLAGER_shard1_replica2
node name:solr6-1:8080_solr
• Replica: core_node2
core:WTLAGER_shard1_replica1
node name:solr6-2:8080_solr
• Replica: core_node3
core:WTLAGER_shard1_replica3
node name:solr6-3:8080_solr
The core numbers und replica number match the number of solr servers
Eg:
Solr7.4, 5 Server with zookeeper ensemble
Shard: shard1
• Replica: core_node3
core:TestCollection_shard1_replica_n1
node name:solr7n4:8080_solr
• Replica: core_node5
core:TestCollection_shard1_replica_n2
node name:solr7n5:8080_solr
• Replica: core_node7
core:TestCollection_shard1_replica_n4
node name:solr7n1:8080_solr
• Replica: core_node9
core:TestCollection_shard1_replica_n6
node name:solr7n2:8080_solr
• Replica: core_node10
core:TestCollection_shard1_replica_n8
node name:solr7n3:8080_solr
The core numbers and the replica numbers are up to 10 (double the amount of
servers)?
It is confusing for me...
Does it matter?
Do I miss something ?
