Hello.

I installed a MongoDB 4.0.4 standalone server in order to perform a migration from Windows to CentOS. After of an unexpected shutdown of the server (virtualization issue) I cannot start a MongoDB server. I perform a repair procedure as described in an documentation: mongod --repair --directoryperdb --dbpath /opt/mongodb/data and assign permissions to mongod again after that by chown.

I added a repair log here.

Any way MOngoDB cannot start and write the following output in the log:
