Replication between On-premises Primary & Secondary Controllers

[#1]

We have two controllers installed with HA. Primary and Secondary

Recently failover happened and Controller is running on Secondary.

As per role my Secondary Node is acting as Primary Controller.

I want to replicate the data from Primary (Role) to Secondary (Role)

where should we run ./replicate.sh ? Node acting as Primary Role  or Node Action as Secondary Role ?

I tried to run it as script on the node which is acting as secondary and getting the below error.

mv: cannot move `/opt/AppDynamics/Controller/logs/replicate.log' to `/opt/AppDynamics/Controller/logs/replicate.log.2021-01-22.11:30:52': Read-only file system

This issue is resolved now. The cause of the issue was - the file system on the node went to read-only mode. Once corrected replication started again.
