> When OM and SCM are colocated and ozone.om.ratis.storage.dir and ozone.scm.ha.ratis.storage.dir are set to the same directory, the OM will incorrectly detect SCM's Ratis group ID and think that were was an erroneous change to the OM service ID.

> java.io.IOException: Ratis group Dir on disk scm does not match with RaftGroupID7f6848f2-63c2-3ce4-a1d2-9e88065dfcc3 generated from service id ozone1. Looks like there is a change to ozone.om.service.ids value after the cluster is setup. Currently change to this value is not supported.
> {code}
> This Jira is to support setting the two configurations to the same directory when OM and SCM are colocated while still maintaining the OM service ID check.
