Hi sneha_k_a, I've examined the provided log files. Unfortunately, this error indicates that the disk corruption affected more than just the WiredTiger.wt file. In this situation, I would recommend checking the integrity of your disks and then restoring from a backup. Kind regards, |

Hi sneha_k_a, Thank you for the report. I've attached a repair attempt of the files you've provided. Would you please extract these files and replace them in your $dbpath and let us know if it resolves the issue? If you are still seeing errors after replacing these files, please provide the complete logs from mongod so that we can further investigate. While this issue is likely related to some sort of disk failure, I would recommend upgrading to the latest version of either MongoDB 3.2 or 3.4 to take advantage of significant improvements to WiredTiger. Kind regards, |
