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 (manager/peers/search heads).

2. On the manager node, 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 manager node.

6. Start the peer nodes and search heads.

Note the following:

• The manager ignores any multisite attributes remaining in server.conf (site_replication_factor and so on).

• Upon restart, the manager 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.
