How to maintain existing replication factors while adding new attributes while migrating from single site to multi-site indexer cluster?

Hi,

We are working on migrating a single site indexer cluster to multi-site indexer cluster. For this, we are using Splunk CLI to set the clustering attributes. We are using the following command:

splunk edit cluster-config -mode master -multisite true -available_sites site1,site2 -site site1 -site_replication_factor origin:2,total:3 -site_search_factor origin:1,total:2

However, running this command removes the existing replication factor and search factor entries that are present in the server.conf file. According to Splunk documentation, the replication and search factor values need to be present in the server.conf file to maintain pre-migration data.

Is there something we are doing wrong? How do we maintain the original factors while adding the new attributes for multi-site?

Thanks,
Keerthana

That command shouldn't overwrite the existing replication_factor and search_factor entries! What version are you running?

(if replication_factor and search_factor are not present, the default values should still be present from the default/server.conf btw. use btool to see what the current actual configs are and what files are providing them)

We are using splunk version 6.4.0. I am aware that replication and search factor entries are present in default/server.conf too but there might be a case where our customer would have set custom replication and search factors in his local/server.conf file.
