MongoDB does not open Port

[Tarun_Gaur]

Hello @Florian_Streppel ,

Welcome to The MongoDB Community Forums!

To understand your use-case better, please share more details such as:

@Florian_Streppel

After the restart of one MongoDB server, the process does not open a network port anymore.

• How did you determine that the port was not opened? Was there an error in the logs?
• What is your deployment topology? If it is a replica set please share the output of rs.status() and rs.conf()

@Florian_Streppel

When I unmap the dataarea

• By dataarea did you mean the dbpath? What does unmap means in this context?
• I don’t see any errors in the logs you shared, could you please share the error you are getting?

I already tried to use the repair command but after it starts, it does nothing to the database, even after running for up to 12 hours.

Warning: Only use mongod --repair if you have no other options. The operation removes and does not save any corrupt data during the repair process and should not be run in a replica set as mentioned in the repairDatabase manual.

If you’re having issues starting and connecting to a self-hosted MongoDB deployment, you might find hints in the following topic:

Error: couldn't connect to server 127.0.0.1:27017

I’ve just read that this issue is common for macOS Catalina users because The new MacOS 10.5 does not allow you, by default to create new volumes in the / subsystem and if you do, they will be deleted on restart. So /data/db can’t be created during installation’s process.
