Can't change dbpath for mongodb

I'm unable to change dbpath for mongoDB (WSL2 Arch), I run the bellow command:

 sudo mongod --dbpath /home/arijit/work/data/

Permission for data folder:

drwxr-xr-x  2 mongodb mongodb 4096 Aug  9 10:00 data/

Error message I'm getting:

I have tried to delete /var/lib/mongodb/mongod.lock file and then run the command for change dbpath but same result.

Based on @Gibbs answer, the error means the port is already in use another process. You can check and confirm this with

ps aux | grep -v grep | grep mongod

The output should look like this

user 73044   0.2  0.2  5501992  17176   ??  S    11:02AM   0:07.32 mongod --config /usr/local/etc/mongod.conf --fork

where 73044 is the PID

You can then kill the process with

kill -9 <PID> # Replace <PID> with the PID provided in the output...in my case 73044

You can now try starting mongod again with

mongod --dbpath /home/arijit/work/data/

Error is different

{"error":{"code":9001,"codeName":"SocketException","errmsg":"Address already in use"}}}

It means port is already being used by another process.

Try checking ps -ef | grep portConfigured. Default mongo port is 27017

If another process is running in the port, then you have to change port by passing --port portNumber while starting mongo.
