I just upgraded from mongodb 3.4 to 4.4, after that the database won't start.
As a service.....
[root#ssdnodes-54313 mongo]# systemctl restart mongod
Job for mongod.service failed because the control process exited with error code.
See "systemctl status mongod.service" and "journalctl -xe" for details.

I want to know why my mongo docker not writing data to local foler. I run my mongo docker with this command:
(/data/db seems to be the mongdo docker's data storage position, and /data/docker/mongo_volume is the folder in the "host" machine)
sudo docker run -it -v /data/db:/data/docker/mongo_volume -d mongo
When the mongo docker successfully started in my host , $docker ps looks like good:
u#VM-0-9-ubuntu:/data/docker/mongo_volume$ sudo docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
5848da7562a3 mongo "docker-entrypoint.s…" 10 minutes ago Up 10 minutes 0.0.0.0:27017->27017/tcp, :::27017->27017/tcp sleepy_clarke
and $ docker inspect <container_id> shows the mounted volume:

{
"Type": "bind",
"Source": "/data/db",
"Destination": "/data/docker/mongo_volume",
"Mode": "",

},
and I check the dockers (in docker shell) /data/db folder, everything looks good:

However, here comes the problem: I found there's nothing in my "host machine"'s /data/docker/mongo_volume:
ubuntu#VM-0-9-ubuntu:/data/docker/mongo_volume$ ll
total 8
drwxr-xr-x 2 root root 4096 Mar 20 13:46 ./
drwxr-xr-x 3 root root 4096 Mar 20 13:46 ../
So anyone could give me a clue? thanks a lot!
your docker command is incorrect, you should place -v <host_folder>:<container_folder>, e.g.
sudo docker run -it -v /data/docker/mongo_volume:/data/db -d mongo
I am attempting to update the dbpath for mongo db. I am following the steps as below:
1) Create new directory : sudo mkdir /mnt/database/mongo
2) Change owner : sudo cp -R /var/lib/mongo/ /mnt/database/
3) Copy DB files: sudo chown mongod:mongod -R /mnt/database/mongo
4) Update mongo configuration file:
storage:
dbPath: /mnt/database/mongo
5) Restart mongod service: sudo systemctl restart mongod
The service restart command gives the following error:
Job for mongod.service failed because the control process exited with error code. See systemctl status mongod.service and journalctl -xe for details.

The Tutorial you are following is for Ubuntu Linux. It looks like you have a Centos Linux. Try this https://www.digitalocean.com/community/tutorials/how-to-install-mongodb-on-centos-7
I have created simple image based on mongo:latest. My Dockerfile is just
FROM mongo:3.3
MAINTAINER developer#encode.cz
Now when I run it by cmd docker run my-mongo mongod I get no /data/db error. But there is clearly RUN mkdir /data/db in mongo base image. Also pure mongo base image works as expected.
Why is this folder not present in my custom image if it is in the base image?
I think you have problems in the way you are testing or I don't understand well your question. I tested the official image:
docker run -d --name mongo mongo:3.3 mongod
docker exec -it mongo bash -c 'ls -la /data/db'

Be aware, the /data/db directory is declared as a volume. If you are having problems withn that, restart the docker daemon and check your available disk space df -h

Running mongorestore failed which never happened to me before. This time I am restoring on a primary server of a two nodes replica configuration:
bash-4.1$ mongorestore mas
connected to: 127.0.0.1

2015-01-16T02:01:50.692-0500 going into namespace [mas.app]
1 objects found
2015-01-16T02:01:50.692-0500 Creating index: { key: { _id: 1 }, name: "_id_", ns: "mas.app" }
Error creating index mas.app: 18825 err: "couldn't create file /mongoDB-data/mas.ns"
Aborted
The result of df -h shows there are still a lot of spaces:

the original files in /mongoDB-data:
