How much storage currently does it take for the nodes to fully sync?
If you are below this storage threshold, are you still able to get rewards even if it is not fully synced?
I believe that your node has to be fully sync’ed before you are capable of earning any rewards.
As for the size needed for one’s node, I’m not near one of my machines;however, they are VM’s such that there’s <60Gb of available drive space given to them and they are supporting the farmers ( with plots on external drives. )
Size of node requirement is currently listed on our docs here Farming with the CLI | Subspace Labs Documentation
Like jeff said, currently ~60GB
You will not be able to fully sync your node if you do not provide ample storage for your node, and thus will never be able to start syncing. (this will be changed with future updates and optimizations)
