Cluster Configuration

Hi,

How can i achieve following.

I have 5 nodes with 30GB RAM in it.

I want to create Index with 5 shards and 1 replica.

I want all primary shards to be in memory and replica on disk.

Also, i want to disable search against replica. So, when user search query goes against shards in memory. Only in disaster situation queries goes to replica.

Thanks in Advance!!

You don't store data in memory in ES, it is only pulled into memory when
querying.
For your queries, check out
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-request-preference.html

Not sure what you are thinking about DR here, but if the primary shard
disappears (ie the node it runs on dies), then the replica is promoted to
primary, which makes your point moot.
