GET ERROR: Moving source lab_to_dr with empty password to preserve replication stream on new master

[peterpan104]

I have two clusters in repman

## cluster 1
Master01
Slave01

## cluster 2
Master02
Slave02

Master02 also acts as a slave to Master01 (using replication source lab_to_dr).

However, when Master02 failed, I received an error message indicating that Slave02 entered an empty password during the 'change master' process.

I was wondering replication manager supports this kind of architecture? I'm happy to provide more information if needed.
