priyeshkaratha opened a new pull request, #9981: URL: https://github.com/apache/ozone/pull/9981
## What changes were proposed in this pull request? This pull request improves how administrators manage deleted blocks in Apache Ozone. It introduces a new command-line tool that helps detect and fix mismatches in the deleted blocks summary. The tool works by taking a snapshot (checkpoint) of the database and comparing the actual deleted blocks with what the system thinks is deleted. If it finds any differences, it clearly shows them to the user and can also fix the issue with confirmation. This makes it easier to maintain accurate data and improves the reliability of the system. ## What is the link to the Apache JIRA HDDS-14387 ## How was this patch tested?
