MongoDB refuse to start, operation not permitted

Question

When I try to run mongod --dbpath=./data I get the following error:

My user is in the vboxsf group.

Does anyone know why I'm getting this error, or what I can do to fix this?

---

I should note that I'm running Debian inside Virtual Box on a Windows 8.1 host. The directory in question is a shared folder (hence the vboxsf group).

Answer 1

Know problem with mongod... It don't work with VirtualBox shared folders. dbPath must be local, NFS, SAN.. Anyway something what is mounted...

A summary of possible solutions are listed below for your convenience:

MongoDB Operation Not Permitted

MongoDB was working perfectly until one day it generated a lock file and stopped starting with the following error:

The corresponding accepted Answer was:

Assuming permissions are correct. It could be an selinux issue, try:

setenforce 0

then try to start the server. If the server starts, you will have to use semanage to set the proper context to the mongo data folder

Windows mounting /data/db

I'm trying to mount /data/db from my Windows dev PC but everytime I try, Mongo crashes as it seems to not have the right BUT :

• I have changed the security parameters in windows to allow everyone to do everything (full access)
• If I mount in a different directory, it works (the container launchs itself and I can write in my directory)

A possible explanation was:

Found a link: VirtualBox Shared Folders are not supported by mongodb.

Apparently one user found a workaround and documented it as:

It works using a volume which is created using docker volume create --name=myvolume The volume name is used instead of the local path. It's just a workaround. To be more precise the line I used in my case :

docker volume create --name=mongodata
docker run -d -p 27017:27017 -v mongodata:/data/db --name=mymongo mongodb:3.3

Mongodb with volume doesn't work (Operation not permitted)

The initial person writing the issue had already determined that it wouldn't work and was in search of a solution.

Mongo docs says For example, HGFS and Virtual Box’s shared folders do not support this operation. https://docs.mongodb.com/manual/administration/production-notes/#fsync-on-directories

I wonder if it is possible to make work on current docker for windows.

There was a link in this case that recommeded tuning the mongodb storage engine:

Doesn't docker plan to implemnt something like this?

No, not right now. You might be able to tweak the mongodb storage engine to work on an SMB share: https://forums.docker.com/t/issues-with-mongo-with-mounted-volume-for-data/15085/4

Summary

There are multiple issues surrounding MongoDB and virtual servers on Microsoft Windows, so you might want to consider running your MongoDB in a *nix environment.

Mr. @o01, I have gone through your error log actually the real error is Cannot start server. The default storage engine wiredTiger is not available with this build of mongod.

what is your installation mongod server path from there you run the below mention command.

Please specify a different storage engine explicitly.

e.g. mongod.exe --storageEngine=mmapv1
