SF and RF never met while adding an indexer to multi-site cluster

[mchang_splunk]

We migrate single site to multisite cluster by following the document:
https://docs.splunk.com/Documentation/Splunk/latest/Indexer/Migratetomultisite

However, SF and RF never met:
Missing enough suitable candidates to create searchable copy in order to meet replication policy. Missing={ site2:1 }
Missing enough suitable candidates to create replicated copy in order to meet replication policy. Missing={ site1:1 }

There is only 1 bucket listed in fixup task, the bucket name is already multi-site bucket name, but still can't meet SF and RF with above message.

Tried:
1. verified GUID is correct as peer and restart everything, not working
2. remove all files in the bucket, only leave /rawdata/journal.gz, then do ./splunk rebuild , not working

What else I can do to resolve this issue?

This is because the bucket has come from a single instance.

To get this to automatically replicate, append the following in the clustering stanza in $SPLUNK_HOME/splunk/etc/system/local/server.conf on the index cluster master;

[clustering]
constrain_singlesite_buckets = false

The root cause is the bucket is marked as single-site ("origin_site" = default):

change default to site1 should resolve the issue
