@aduffeck @butonic Did you see that?

The problem seems to be the missing id cache, The posix driver requires a shared cache so that storageprovider and dataprovider can always look up the paths for all ids.

Adding something like

      STORAGE_USERS_ID_CACHE_STORE: "nats-js-kv"
      STORAGE_USERS_ID_CACHE_STORE_NODES: "localhost:9233"

to your docker-compose.yml should fix the problem. And once cs3org/reva#4779 has been merged the driver will refuse to run without a shared cache.
