Docker overlay2 uses entire disk space

[Alexey]

Hello @Dozoris,
You may configure logs for docker:

@Bivvo

    --log-opt max-size=1g \
    --log-opt max-file=5 \

or configure storagenode to place logs to the disk with data: How do I redirect my logs to a file? - Storj Docs

You also may check the space usage by docker:

docker system df
