There may be other ways, easiest way is to write a script that gets the cluster
status, and for each collection per replica you will have these details:
"collections":{
“collection1":{
"pullReplicas":"0",
"replicationFactor":"1",
"shards":{
"shard1":{
"range":"80000000-8ccbffff",
"state":"active",
"replicas":{"core_node33":{
"core”:"collection1_shard1_replica_n30",
"base_url":"http://host:port/solr";,
"node_name”:”host:port",
"state":"active",
"type":"NRT",
"force_set_state":"false",
"leader":"true"}}},
For each replica of each shard make a localized call for numRecords:
base_url/core/sleect?q=*:*&shard=shardX&distrib=false&rows=0
If you have replicas that disagree with each other with the number of records
per shard then u have an issue with replicas not being in sync for a collection.
This is what I meant when I said “replicas out of sync”.
Your situation was actually very simple :) one of you collections has less data.
You seem to have a sync requirement between collections which is interesting,
but thats beyond solr.
Your inter collection sync script needs some debugging most likely :)
