Okay, I am having some trouble with Arktika. When I start up the worker the snowfield seems to load okay but after I get to subscribing to work I get connection refusal errors:

On the worker node

On node1 it doesn't find the snowfield:

Not in sources.

So why is the GRPC server unavailable?

Need file source for memory chunks

`layer_20_type=file` `layer_20_path=/home/arktika/snow` `layer_20_threads=0`

that is in the node1.conf

You have 20 layers?

yes

Each node needs filesystem access to the chunks

NFS is fine

I don't give filesystem access by specifying the path to the worker-- ah so I have to install a file server where the snowfield is located?

Yeah I have my main server be nfs server for the smaller nodes
