Stuck on stopping array (6.8.3 trial)

We setup a new unraid system using a repurposed motherboard with 2 new Seagate Ironwolf drives. After the setup was done, we started to copy data from a Windows Server to Unraid.  After the first drive was copied, we mounted a old 2nd data drive as Disk 2 and after formating, started to copy again.  However during the middle of the copying, the system seems to have crashed and the original Disk 1 was empty with the Unmountable message.  Making a rookie mistake, we just formatted Disk 1 again and started copying again.  But since the copying over the network was slow, we decided to mount the drive as an Unassigned drive and copy from an ssh terminal and using Midnight Commander. 

 

The copying started out fine, copying them one directory at a time until we started copying a directory which has about 130gb of data.  We left the system to copy and when I came back I saw the eror screen below

After aborting, I came to the copying screen that indicated a segmentation fault error.

So I tried to stop the array but it doesn't seem to work.  I tried to reboot but even though I was kicked out of the ssh session, I logged back in with the system still running.  It has not actually rebooted.  The load on the system is currently still at 3.00.

We cannot do a hard reset since we are accessing it remotely while copying.  
Also, we are worrying that if after the reboot, we might again encounter loosing a disk or worse, data.

Any advise on what we might be doing wrong?  

 

Attached also the diagnostic file. 

 

Appreciate any advice.  TIA.

You might need to force a reboot, also lots of ATA errors from disk1, start by replacing cables.
