How to compute index size

[Mohammed Farhan Ejaz]

Hello All,

I want to size the RAM for my Solr cloud instance. The thumb rule is your
total RAM size should be = (JVM size + index size)

Now I have a simple question, How do I know my index size? A simple method,
perhaps from the Solr cloud admin UI or an API?

My assumption so far is the total segment info size is the same as the
index size.

Thanks & Regards
Farhan

Solr Backup restore

[Mohammed Farhan Ejaz]

Hello,

I have a Solr Cloud with 2 node cluster. It has 2 replicas one on each node
with a single shard.

The cores created are <>_shard1_replica1 and
<>_shard1_replica2.

When I create a collection back up and restore the documents are indexed
properly on both the nodes, but the cores created are
<>_shard1_replica0 and
<>_shard1_replica1

Additionally, when I delete or add documents it gets only deleted from one
node which means the replication does not work. I noticed on one node I do
not have the index folder on one of the nodes from where document is not
getting deleted or added.

What could I be possibly doing wrong?
