--------------------------------------------------------
In HDDS-12206 the {{read-replicas}} tool was replaced with {{{*}ozone debug
replicas verify{*}.}}
{{So with these changes we are able to run the command ozone debug replicas
verify on all OM,SCM hosts.}}
{{and the --output-dir is not relevant anymore (HDDS-13248), as ozone debug
replicas verify}} will write json to stdout by default.
