Mongod.service start command is not working after db path move

Ops and Admin

Below steps I followed to move the mongo db path from one location to other

1.Stop MongoDB services
sudo systemctl stop mongod.service

2.create a new directory in separate partition
mkdir /data/mongoDB/mongo

3.Make sure that mongod user has privileges to read / write from that directory
chown mongod:mongod -R /data/mongoDB

4.Copy the data folder of your old mongodb location to the new location
cp -R /var/lib/mongo/* /data/mongoDB/mongo/

5.create a copy of /etc/mongod.conf – for backup purpose

  1. change to new location of below variables in /etc/mongod.conf

path:
dbPath:
pidFilePath:

  1. change the pid file location in mongod.service file
    /usr/lib/systemd/system/mongod.service

  2. Run below command to reflect changes done
    systemctl daemon-reload

8.Start mongodb services
sudo systemctl start mongod.service
Job for mongod.service failed because the control process exited with error code. See “systemctl status mongod.service” and “journalctl -xe” for details

NOTE-

  1. i checked the log file and there was no error registered after mongod shutdown
  2. i checked journalctl log file and below line appears
    ERROR: child process failed, exited with error number 1**
    To see additional information in this output, start without the “–fork” option.**

i used below command and mongodb started functioning
mongod --confog=/etc/mongod.conf

CAN YOU HELP HERE…AM I MISSING ANYTHING AND HOW CAN WE FIX mongod.service status???
