 Description   

Hi,
I have to repair a mongodb-Setup. After server crashed. I tried to --repair but I got a error.

So I tried to recover using the wt-Tools, but still, I got the same error. Every command used wit wt tools gives me the same.
So now, I have no idea how to repair that file. I put the WiredTiger.wt and WiredTiger.turtle into the Attachment box.

Glad to hear you're back up and running godstory. I'd strongly recommend you consider using a replica set and keep current backups of your data.

Thanks,
Ramón.

Sorry to hear you're having issues. I've run a repair attempt and uploaded the result. Please extract it on your dbpath and try to start mongod.

Please note there's no guarantee this may work – whatever caused this issue (typically unclean shutdowns and flaky storage) may have caused more damage than can be repaired.

Regards,
Ramón.
