Where did my space go?

My 6TB EX2 suddenly showed that I had 37MB left! This was after the FW update. I can file explorer into shares subfolders. I have checked each share and see I have about 1.4GB of total data. I used TreeSize Free to scan the drive and it sees the same amount of data. I have rebuilt the directory. I read multiple post and have ssh into the device and this is the report:

Any ideas will be appreciated
I am also having issues when I try to move large files from the device to PC. The system freezes and I loose dashboard access. Will not allow a log on and the I cannot see files via file explorer. I have let the device be for up to 2 days to see if it will clear on its own. I just have to eventually cut power.
This device is just a couple of months old and I want to make this work.
Thank you in advance for any assistance.


After the firmware update, did you tried resetting the unit? If not, please try that.

You can run a system only restore that will not remove any data from the unit or a physical reset using the reset button on the back of the unit.
