After power failure, 2 MongoDB Servers just won't start again. WiredTiger error (0) [1500732904:16506][17102:0x7fc3ddb5bdc0], file:WiredTiger.wt, WT_CURSOR.next: read checksum error for 12288B block at offset 2478080: block header checksum of 405166289 doesn't match expected checksum of 439830749 Would you be willing to try repairing our .wt files for both our servers separated by 2 set of files that i've attached |

Thanks for the additional information, from your responses this issue appears to be the result of a disk corruption outside of MongoDB following the power failure. |

Hi zhaow7, Thank you for the report. I only see one set of files, and I've attached a repair attempt of them. 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. Additionally, would you please answer the following questions:
Thank you, |
