Thanks for reporting the issue.
The Datanodes can only contact the SCM with the same cluster ID. while
moving the SCM, the metadata directories were also copied as well?
Thanks,
Mukul

Hi all,
I would like to discuss https://issues.apache.org/jira/browse/HDDS-6634

During our internal Ozone testing, we noticed that a datanode can be connected
to another cluster (not the one the datanode had been initialized with).
Although the conditions needed for issue reproduction are rather special (new
SCM must have the same IP as the old one), theoretically there might be cases
(like DNS spoofing) to hit it in a production environment. The idea of SCM
processing another cluster's datanode reports seems catastrophic to me.
