Here's an update: went through several cycles of leaving it alone for a few days, while it was stuck, GUI stopped responding, sometimes it would take down the whole LAN, unplug network cable LAN restored, hard reset Unraid server.
After going through several cycles of this, the drive somehow appeared as Online and wrote 56GB of data. Now we have a new problem, whenever we start the array, it proceeds through to Array Started, but soon after the GUI becomes unresponsive. If left alone, it eventually leads to Unraid taking down the whole LAN, requiring us to unplug the network cable and hard reset Unraid.
Attached is the diagnostic pulled before starting the Unraid, we will try to get the diagnostic while the GUI is hung up...
