Recover mongodb after unexpected shutdown

Today I’m relaunching my Uptime Monitoring using NodeJS for uptime.web.id which is powered by Fiberoute. But due to bad configuration for the networking I did, the server had to shutdown from the SolusVM manualy.
My Mongodb crashed after the server boot, and never work again. From the log files, we need to repair it,  but we have to remove the mongod.lock first.

# rm /var/lib/mongodb/mongod.lock
# mongod --repair
