Will you place an unmanaged switch between the target computer and the building switch? Your issue could be spanning tree is enabled, but you are not using one of the fast spanning tree protocols (i.e. RSTP, MSTP, fast-STP, etc).
If that doesn’t work then schedule a debug deploy (tick the debug check box before you submit the deploy task). PXE boot the target computer. After a few enter key presses it will drop you to a linux command prompt on the target computer. Run the following commands.
ip addr show
Ensure eth0 has an IP address. Then attempt to ping your fog server.
I would like to appreciate this nice little post, I wish I had stumbled upon this earlier. Last week I tried creating my Synology NAS as a storage node and it worked. Little did I know that was the beginning of my misery. Whole week I struggled in fixing the replication issues.
Had I found this Thread earlier, I wouldn’t have attempted it.
