RavenDB 4 on Docker - unable to create database on mounted host volume

[Sean Duffy]

Hi there,

I'm attempting to run a RavenDB 4 a docker container.

I've mounted a volume from my Windows host machine (I'm running Docker via Quick start in a VirtualBox VM under Windows 10).

This is the image I'm using along with the command to run the image (RavenDB build 4.0-40012) and mount a folder:

docker pull pizycki/ravendb4

docker run -it -p 8080:8080 -v //c/Users/duffys:/mountdata pizycki/ravendb4

I then connect to the Raven UI and create a new database under the mounted volume, but the database fails to start. (See attached create.png for the paths I am specifying)

Here is the stack trace that shows up in the error:

}

The actual DB folder does get created in my mounted volume on my docker host in Windows though - I can see it created with the same name I specified for the DB name, and it contains a few files and folders including Raven.voron under "Subscriptions". So it doesn't seem related to permissions as it is able to write some new files and directories.

I looked up the EINVAL error code for linux, and that is apparently "Invalid argument".

Does anyone have any ideas as to what is wrong here, or has anyone else successfully created a database on a mounted host volume for a RavenDB4 container?
