You configure the site replication factor with the site_replication_factor attribute, which resides in the master server.conf file. This attribute resides in the [clustering] stanza, in place of the single-site replication_factor attribute. For example:
[clustering] mode = master multisite=true available_sites=site1,site2 site_replication_factor = origin:2,total:3 site_search_factor = origin:1,total:2
Here is the actual syntax required:
site_replication_factor = origin:<n>, [site1:<n>,] [site2:<n>,] ..., total:<n>
Where:
- <n> (positive integer indicating the number of copies of a bucket)
- origin:<n> (sets the minimum number of copies of a bucket that will be held on the site originating the data in that bucket)
- site1:<n>, site2:<n> ...
