Can't create account in clustered configuration

I read this: Adding Users To Dremio

The shared network drive is mounted at /var/dremio/data

I created the directories found in the install under data:

mkdir /var/dremio/data/db
chown -R dremio:dremio /var/dremio/data/db

mkdir /var/dremio/data/pdfs
chown -R dremio:dremio /var/dremio/data/pdfs

mkdir /var/dremio/data/zk
chown -R dremio:dremio /var/dremio/data/zk

But it still doesn’t work. Do I need to create the second level directories found under db (catalog, metadata, search) and/or the files under pdfs/zk?
