How to fix "Error: storagenode configuration already exists (/app/config)"

I am trying to set up a small node and am stuck at the docker step. The storagenode configuration already exists. Is this a problem? How do I reset it?

$ sudo docker run --rm -e SETUP="true" \
    --mount type=bind,source="/home/james/.local/share/storj/identity/storagenode/identity.cert",destination=/app/identity \
    --mount type=bind,source="/mnt/2tb_small_slow/storj",destination=/app/config \
    --name storagenode storjlabs/storagenode:latest

Error: storagenode configuration already exists (/app/config)

Note that the file mentioned as the configuration doesn’t seem to exist. I presume docker is using some relative path?

 $ cat /app/config/config.yaml
cat: /app/config/config.yaml: No such file or directory
ls /mnt/2tb_small_slow/storj/config.yaml

is the path inside the container.

Perhaps you already did the setup once. If so, you should not do it in the second time.
