      Description

      My MongoDB server crashed and I can't start the mongod service. I'm using this command to try to repair database: mongod --dbpath . --storageEngine wiredTiger --repair

      Mongod version was 3.0.2, but i tried to upgrade to 3.0.4 and repair again, but gave the same error.

      I researched a lot of ISSUES and did so many things to try to recover my entire database but nothing works. I can't find ways to ignore corruption in collections (loss some data) but recover some part of them.

      Error when I try to repair:
