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

Chinmaya_Das · January 6, 2022, 5:57am

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

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

path:
dbPath:
pidFilePath:

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

i checked the log file and there was no error registered after mongod shutdown
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???

@Fabio_Ramohitaj any idea, how to fix
suprisingly in some servers it is working, and some doesnot

Chinmaya_Das · January 7, 2022, 4:12am

we tried below options as well, still not working

Option 1:

server reboot

Option2:

remove mongod.lock file

*repair mongo db with below command

mongod --dbpath /data/mongoDB/mongo –repair

Hi @Chinmaya_Das,
Unfortunately I’m out right now and I have no way to do a test, but I can advise you to check if all the paths in the configuration file are correct.
The problem is that the exit status 1 is a too generic error and it happened to me when I had a wrong path in the configuration file or a wrong option or a wrong indentation .

Best regards and keep me updated.

Chinmaya_Das · January 10, 2022, 3:55pm

surprisingly in few servers it is working, and in few servers it is not

I tried to replicate and cross check the permission, indentation, path ownership everything
still issue persists

Fabio_Ramohitaj · January 10, 2022, 5:49pm

Hi @Chinmaya_Das ,
I haven’ t any idea,
we can try to ask @Stennie or @chris for help .

Regards

Chinmaya_Das · January 11, 2022, 4:52pm

@Stennie @chris --can you assist

Stennie · January 11, 2022, 6:05pm

Hi @Chinmaya_Das ,

I’d strongly discourage option #2 per the warnings in `mongod --repair’ documentation:

Only use mongod --repair if you have no other options. The operation removes and does not save any corrupt data during the repair process.

Avoid running --repair against a replica set member:

To repair a replica set member, if you have an intact copy of your data available (e.g. a recent backup or an intact member of the replica set), restore from that intact copy instead(see Resync a Member of a Replica Set).

If you do choose to run mongod --repair against a replica set member and the operation modifies the data or the metadata, you must still perform a full resync in order for the member to rejoin the replica set.

If mongod fails to start as a service but runs via manual invocation with the same config file, my guess would be that there is a problem with file or directory permissions that you are avoiding by running mongod as the root user. I would check permissions for any paths mentioned in your /etc/mongod.conf (step 6).

If permissions aren’t the issue, I’d try this suggestion.

If you’re still stuck, please share more details including:

specific version of MongoDB server
type of deployment (standalone, replica set, or sharded cluster)
O/S version

Regards,
Stennie

i am running below commands using mongod user ( not via root)

mongod -f /etc/mongod.conf
systemctl start mongod.serice

steevej · January 12, 2022, 2:27pm

Need output of

ls -l /data/mongoDB/log/
ls -l /data/mongoDB/mongo/

If mongod was started by root, it is possible that the log file is now own by root and cannot be overwritten by user mongod.

You will need to share the content of the log file because everything looks fine.

More commands to run:

cat /data/mongoDB/mongod.pid
ps -aef | grep [m]ongod
ss -tlnp
ls -l /tmp/mongo*

steevej · January 13, 2022, 3:33pm

You have to do one or the other. Not both. If you start mongod once manually, it won’t start as a service because it is already running.

santiago_miranda1 · January 13, 2022, 6:32pm

I’ll try not to add noise to the post, but normally running from CLI with the --fork option, and the same yaml configuration file (commenting # the fork) throws some good information to start troubleshooting.

Also, including the logs after starting the service, even though you believe it’s not relevant, it may be useful. Because error status 1 is thrown by systemd but does not correspond to a mongod error afaik

Hi @Chinmaya_Das

Is SELinux enabled? If it is change the SELinux mode to permissive and try again.

If you need SELinux then moving the directories around while not difficult become non-trivial.

~~I think I have posted about it before or it may even be documented alrady.~~

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

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

i am running below commands using mongod user ( not via root)

SELINUX=permissive
