Description:
Hi,
My MongoDB service did not start automatically on System reboot from AWS console. To figure out the issue I logged in to the EC2 instance and following are the result of various commands. Still MongoDB is not starting. I am really stuck here.

1.sudo /opt/bitnami/ctlscript.sh status

Cannot find any running daemon to contact. If it is running, make sure you are pointing to the right pid file (/var/run/gonit.pid)

After above error I ran following command:

2: sudo /opt/bitnami/ctlscript.sh start

Starting services…
Job for bitnami.service failed because the control process exited with error code.
See “systemctl status bitnami.service” and “journalctl -xe” for details.

3. systemctl status bitnami.service

Can not figure out what s stopping from MongoDB to start. Note that it was working system which suddenly stopped after reboot.

I also checked the diskSpace for any issue and that seems to be ok :

sudo fdisk -l

Disk /dev/nvme0n1: 50 GiB, 53687091200 bytes, 104857600 sectors
Disk model: Amazon Elastic Block Store
Units: sectors of 1 * 512 = 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: 77DF7ADC-D0A3-1649-900D-5F83E184311A

Partition table entries are not in disk order.

Please help.

To Add, I also do not see the data folder when connected to console as bitnami user. where can I locate data/db folder.

when I run Mongod command from console I can see this error as well:
“c”:“STORAGE”, “id”:20557, “ctx”:“initandlisten”,“msg”:“DBException in initAndListen, terminating”,“attr”:{“error”:“NonExistentPath: Data directory /data/db not found. Create the missing directory or specify another path using (1) the --dbpath command line option, or (2) by adding the ‘storage.dbPath’ option in the configuration file.”}}

Hi @prasoon.rana,

The gonit service takes some time to be started. However, you can start the services by running these commands

sudo gonit
sleep 10
sudo gonit status
sudo /opt/bitnami/ctlscript.sh start
for file in `find /opt/bitnami/scripts/ -name start.sh`; do sudo $file; done

All the MongoDB information is inside the /opt/bitnami/mongodb folder. However, the data folder is symlinked to this other one: /bitnami/mongodb/data/db

Happy to help!
