Fix error: mongod dead but subsys locked

I use mongodb v3.2 on CentOS 6, just restart mongod service and got error mongod dead but subsys locked . Humm…

How I fixd it.

1. Stop service mongod: service mongod stop
2. Add following in config file: vim /etc/mongod.conf

storage:
   mmapv1:
      smallFiles: true

Same in my mongod.conf file

3. Restart mongod service: service mongod restart — config /etc/mongod.conf

That’s it!
Happy coding
