> Key: HDDS-10567
> URL: https://issues.apache.org/jira/browse/HDDS-10567
> Project: Apache Ozone
> Issue Type: Improvement
> Components: Ozone Recon
> Reporter: Mohammad Arafat Khan
> Assignee: Mohammad Arafat Khan
> Priority: Critical
>
> From recent User experiences it has been observed that issues often arise
> related to cluster health or roles, particularly those of OM and SCM. Here
> are the various scenarios identified:
> Scenario 1:
> Recon encounters difficulties fetching the OM/SCM DB snapshot due to issues
> with OM/SCM roles. However, the User tends to report a recon issue because of
> this. Even though its clearly OM side fault.
> Scenario 2:
> Upon fetching the full or last fetched snapshot, Recon scans the Snapshot
> DB's of SCM and OM. If these snapshots are found to be empty, it may indicate
> a problem with data availability or synchronization. In such cases, an alert
> should be triggered to notify users accordingly.
> Possible Solution:
> Implement a mechanism to show a warning message on the Recon UI Dashboard in
> case OM/SCM is down or unable to fetch updates from the OM side, or if the
> updates are empty.
