There’s a great tutorial to setup on connecting multiple machines on the same network.
Key part of this is importing the CA correctly, and setting config host harvester IP to your full node (in your case the DS918+.
As far as no found plots, check the logs. If you see “Found 1 proofs” and you have no rewards, you likely are having slow proof checks.
There is now a WARNING shown in the log (as a result of the above) about “something something if this happens more than 5 seconds, you lose.” Find that and if you see this a lot, that’s bad.
You should follow this. As you DS918+ is your main that should be the Farmer and a Harvester, as it has lots of storage. Then you hook up the HPZ440 and E3-1230v2 box as harvesters and plotters. Do not run multiple full nodes on the same network. It is also a resource waste to do so.
In short on this:
DS918+ - Run the GUI
HPZ440 - Run the harvester via command line (if any local storage), run something like SWAR for plotting. Set destination directory to DS918+ if that is where the main storage is, and don’t run harvester if no local storage on that box
E3-1230v2 should be doing the same as above, harvester + plotter
As far as transferring over plots to your NAS with 1gbit, it fine. 10gbit won’t have a lot of upside for you if that’s your question.
The 1% plots, check your plotting logs. It will tell you why what happened and when. Check those.
Also stop using the GUI, scheduling via plotman or SWAR is highly superior.
on the DS918+ you would not put Docker on it, but a virtual machine with Ubuntu Server? (The operating system is Synology’s own interface which only allows a few packages to be installed.)
Would you also integrate the NAS there via the network?
On the DS918+, it is really dealer’s choice here. You want to make this the full node and that can of course be done in the way you are proposing. As the DS918+ is not appropriate for plotting, making it the dedicated farmer is a given.
I’d probably be running Ubuntu Server (No GUI, CMD only) and just running the farmer and harvester via command line. Lowest utilization, very simple, etc. Then just view logs once in a while. GUI just provides a lot of good info in one place that I do appreciate. Not a lot of loss there.
