I have two Truenas systems. A main and a backup. I got my backup going and am transferring data from main to backup. The large file transfer is messing with my main truenas. I first noticed that plex stopped working. then i couldn't get to the web interface to see what is going on. It just says "Connecting to TrueNAS ... Make sure the TrueNAS system is powered on and connected to the network." It is still connected because i can see the file transfer still taking place on my backup device. I can also still ping the main truenas. I thought maybe the output was causing issues which is why plex is not working. I purchased two sfp pcie cards and put those into both truenas boxes and have them connected peer to peer and have RSync set up to use that nic for file transfers leaving the main nic open for everything else. I kicked off Rsync and i've lost plex again and can no longer get into the web interface on the main truenas. I plugged a monitor into the main truenas and am seeing the following error, "freenas.local collected 3066 - - plugin_dispatch_values: Low water mark reached. Dropping 100% of metrics". Any help would be appreciated. I just upgraded from Freenas and didn't have any issues like this. This isn't just an issue with Rsync either. If i file share into each device from a windows machine and transfer files that way i have the same issue. Here are the specs of my main device.
