Splunk Search

What values should I use for replication and search factor in a Splunk multisite indexer cluster with one peer in site1 and two peers in site2?

Hi!

I'm trying to configure a multisite indexer cluster with two sites; site1 and site2. There are one peer in site1, and two peers in site2. I don't think I quite grasp the concept of replication_factor and search_factor vs. site_replication_factor and site_search_factor. I want to set both site_replication_factor and site_search_factor to origin:1,total:2, and in that way keep one copy on the original site, and one on the other site. Also, I want to have the copies fully searchable, so I have to set replication_factor=2 and search_factor=2, right? When I use these values (see code sample below) I get Search Factor is Not Met and Replication Factor is Not Met errors, while when using replication_factor=1 and search_factor=1 everything seems fine. What does this mean using these values considering replication and search? any help would be much appreciated! 🙂


server.conf on master:

[clustering]
available_sites = site1,site2
mode = master
multisite = true
pass4SymmKey = $1$/UusYBk6nI5J
replication_factor = 2
search_factor = 2
site_replication_factor = origin:1,total:2
site_search_factor = origin:1,total:2

In multisite env site_replication_factor and site_search_factor are in use. The legacy replication_factor and search_factor are meant for single site cluster. You can leave these single site values as 1.

To achieve 2 searchable copies in your multisite env, your current setting is accurate.

site_replication_factor = origin:1,total:2
site_search_factor = origin:1,total:2
