Should rrdcached use different rrd directory than main container ?

[hugalafutro]

Hi,
let me preface this by saying I've only passing understanding how most of this works. After #124 closed I re-enabled rrdcached container and noticed it created new directory ./rrd for rrd files. Is this intended? As this restarted graphing and left over gigabytes of "old" rrd files in ./librenms/rrd

I copied the ./librenms/rrd files over ./rrd and got all the old data back while keeping rrdcached working. Inspecting examples/rrdcached-server/docker-compose.yml I can see that it defines these for rrdcached container

    volumes:
      - "./rrd/db:/data/db"
      - "./rrd/journal:/data/journal"

but uses these for librenms container:

    volumes:
      - "./librenms:/data"

I was just wondering if these should be different or should they be same and in any of those cases why? And can I delete the ./librenms/rrd files? Thanks!

If I recall correctly it will use internal rrdcached and write to /data if you don't define an external RRDCACHED_SERVER.
