Solution:  

•  Download the oak-run-1.x.x.jar version matching with your running instance.
• Stop the instance and navigate to path of downloadded jar file
•  Preform the consistency check with below comamnd

              java -jar oak-run-1.6.x.x.jar check /path/to/crx-                                                                  quickstart/repository/segmentstore

 It will traverse backward to find the good state of the segments.

• Revert the repository to this revision by editing ./crx-quickstart/repository/segmentstore/journal.log and Remove all lines after the line containing the latest good revision.
• Delete all ./crx-quickstart/repository/segmentstore/*.bak files.
• Run checkpoint clean-up to remove orphaned checkpoints: 

             java -jar oak-run-1.6.x.x.jar checkpoints /path/to/crx-                                                      quickstart/repository/segmentstore rm-unreferenced

• Finally run the compaction command to compact the repository

             java -Xmx6000m -jar oak-run-1.6.x.x.jar compact /path/to/crx-                                         quickstart/repository/segmentstore
