How to change mongodb data directory ubuntu-CodePudding

I want to change my mongodb data directory to my external media. I have done a lot of search and tried many ways, but could not achieve it. The problem is that when I change data dir to my media (other than home dir), it does not work, but it works for home dir:

I follow these steps:

sudo nano /etc/mongodb.conf

Then, changed:

# Where and how to store data.
storage:
  dbPath: /home/nimashiri/mongodb
#  engine:
#  wiredTiger:

Then:

sudo chown mongodb:mongodb /home/nimashiri/mongodb

When I try for my disk dir, it gives the following error:

● mongod.service - MongoDB Database Server

Any idea?
