| Description |
|
to repro: 1) start up a mongod with --storageEngine=wiredTiger
The file that it looks for is actually in journal/ within the specified path, but the WT command won't look in there. It still won't work even when trying to specifically point it to journal/ :

johny, it seems your dataset is corrupt, and mongod is not able to repair it. As Michael pointed out, for MongoDB-related support discussion please post on the mongodb-user group or Stack Overflow with the mongodb tag, where your question will reach a larger audience. A question like yours involving more discussion would be best posted on the mongodb-user group. See also our Technical Support page for additional support resources. Regards, |

Thanks Michael... but I actually tried mongod --repair both on windows and linux mongo installation. During repair mongo crashes : 2016-05-26T16:49:18.438-0600 I - [initandlisten] ***aborting after invariant() failure |

johny, the original issue reported here is specific to backups, so it is not relevant to the error you are getting. A better forum for your question is the MongoDB user list https://groups.google.com/forum/#!forum/mongodb-user – my first question would be why not use mongod --repair, which will run a salvage on any collections that fail validation. |
