Hi all,
So I tried to recover using the wt-Tools, (described here: http://www.alexbevi.com/blog/2016/02/10/recovering-a-wiredtiger-collection-from-a-corrupt-mongodb-installation/) but still, I got the same error. Every command used wit wt tools gives me the same. Helps and hints are very much appreciated, |

Hi ccornel, Thanks for reporting this issue, so we can best address the issue that you've encountered. Would you please open a new ticket and attach the files there? Please be sure to include the version of MongoDB, the log message describing the failure, and a description of the events (e.g. power failure) preceding the corruption? Thanks again, |

Hi Watching this forum, I have reviewed that I have the same problem described here. And I could not give you a solution, I wanted to ask if you could see my files and be able to repair the error. Thank you , regards. |

Hi jm@mpex.de, I'm glad you were able to salvage the other collection files. WiredTiger.wt contains essential metadata for interpreting other .wt files. Unfortunately, the current process to repair these files is not ready for public consumption.
Kind regards, |

Hi jm@mpex.de, I've attached the repair-attempt.tar containing the WiredTiger.wt and WiredTiger.turtle after a repair attempt. Please extract them in your dbpath and try starting mongod. Kind regards, |

Hi Ramon, of course, I attached it as well. well, the process did nothing as the error was the same as with mongodb --repair. After that it was the same. |

jm@mpex.de, for us to attempt a repair we'll also need the WiredTiger.turtle file, can you please upload it as well? Please note there are no guarantees here, as I can't vouch for the process described in the link you sent. Thanks, |
