Few days back my mongod crashed. It's a single node machine storing about 1 TB of data. The machine is ubuntu 16.04 and mongodb version is 3.4.2. The directory has all files intact.
When I try to start mongod again, I see these log entries:

- This is it. Nothing else happens. The mongod stays like this for hours. When I use --repair option, this behavior persists.
- The reason I'm using different port other than 27017 is because another mongod is running.
