Convert a multisite indexer cluster to single-site

You can convert a multisite indexer cluster to a basic, single-site cluster. When you do so, all peers and search heads become part of the implicit single site.

1. Stop all cluster nodes (master/peers/search heads).

2. On the master, edit server.conf:

a. Set multisite to false.
b. Set the single-site replication_factor and search_factor attributes to implement the desired replication behavior.
c. Remove the site attribute.

3. On each search head, edit server.conf:

a. Set multisite to false.
b. Remove the site attribute.

4. On each peer, edit server.conf:

a. Remove the site attribute.

5. Start the master node.

6. Start the peer nodes and search heads.

Note the following:

  • The master ignores any multisite attributes remaining in server.conf (site_replication_factor and so on).
  • Upon restart, the master picks a primary copy for each bucket.
  • After the conversion, any bucket copies that exceed the single-site replication factor remain in place. For information on removing these extra copies, see Remove excess bucket copies.
  • Future bucket replication and bucket fixing will follow the values set for the single-site replication and search factors.

For information on how to convert a single-site cluster to multisite, see Migrate an indexer cluster from single-site to multisite.
