[jira] [Updated] (HDDS-15454) Tool to Identify Orphan(wrt scm), Duplicate and Deleted-but-Present Containers in Ozone
[ https://issues.apache.org/jira/browse/HDDS-15454?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sreeja updated HDDS-15454:
--------------------------
Description:
Develop a CLI-based diagnostic tool under the Ozone debug framework to analyze container consistency between on-disk container directories on a DataNode and SCM metadata. The tool will identify:
* Containers present on disk but not tracked in SCM (Orphan Containers wrt SCM).
* Containers marked as *DELETED* in SCM but still present on disk(under /current) (Deleted-but-Present Containers).
* Duplicate container directories for the same container ID across multiple storage volumes on the same DataNode.
The tool should provide a standardized, reusable mechanism for detecting and reporting inconsistencies.
