Mounting volume in a container not working

Im on Amazon AWS and can start an image and mount a volume from the root partition, not a problem.

docker run -d -i -t -v /blah/:/blah busybox sh

Inside the container , i can see my files on the host machine in “/test”

However with a mounted disk i have added to the machine, if i mount it, the contents is not visible inside the container.

docker run -i -t -v /mnt/vol1/blah/:/blah busybox sh

Here are the host disks


Filesystem 1K-blocks Used Available Use% Mounted on
/dev/xvda1 8123812 7358972 664592 92% /
devtmpfs 2016364 96 2016268 1% /dev
tmpfs 2024936 0 2024936 0% /dev/shm
/dev/xvdf 20511356 45000 19401396 1% /mnt/vol1

I’ve checked the output of docker inspect, and they both look very similar.

    "Mounts": [
            "Source": "/mnt/vol1/blah",
            "Destination": "/blah",
            "Mode": "",
            "RW": true,
            "Propagation": "rprivate"

Is there some issue im not aware off, such a file system? permissions? or switch you can configure to allow other drives to be mounted in the containers?

Thank you in advance


Problem solved.

You have restart the docker daemon to see these mounts on Amazon.
