CIFS share stopped working after canceled transfer

[r3dh3adkid]

I was transferring a few TB of data between folders in Windows 10 using TeraCopy. I had another copy queued after the first one. I was copying data and running a CRC check on 1.6TB of data. I canceled the second after the first one finished. The second transfer made it a few hundred MB in before I canceled. After I canceled, TeraCopy hung and would not close. I waited around 30m before I forced the task to end. Right after, my CIFS shares stopped working. I received an error about broken disc from windows, but did not screen shot the message. I could not open the share folder or access the share from the Network menu. I have a ubuntu server that has the same dataset mounted via NFS and is working fine. The web panel loads fine and the server is pingable from Windows.

I have tried: restarting my pc, restarting the FreeNAS server, deleting and remaking the CIFS share, restarting CIFS service, deleting and remapping the network share, turning on guest access.

I'm not sure what to try next and looking for any suggestions on where to start.

Environment:
Windows 10
FreeNAS 9.10.1 (d989edd)
SMB2.0 share (I think)

FreeNAS Server:
ASRock C2750 board
Intel Avoton(Atom) C2750
8x3TB WD Red
32GB DDR3 ECC

Not sure why this is showing that PC. I'm positive it's mounted through NFS

Mounting the same mountpoint in both NFS and CIFS? As stated in the manual, this is not a good idea, and can lead to pernicious locks, etc. In fact, I bet something like that happened here.

Troubleshooting steps I'd recommend:

First method:
1) Go in the services menu of FreeNAS. Turn off *ALL* file sharing methods, so BOTH the CIFS and the NFS.
2) Remove ALL mounts of that dataset
3) From your Windows box, just mount something else entirely via CIFS, from another box entirely. Rule out a problem with Windows.
4) Re-establish your shares and re-enable the services.
5) See if you have a problem.

Second method:

1) Go to ANOTHER Windows computer. Attempt to mount the same mountpoint via CIFS, raw, not with whatever copy software you were using.
2) If this does not work, clearly the problem is on the FreeNAS side, or PEBKAC.
3) If this DOES work, then clearly the problem is on the other Windows computer's side, or PEBKAC.

Based on your nickname, and the fact that you are mounting the same datasets using different conflicting file sharing methods, and so on, I think PEBKAC is a likely causative element. :) But good luck sir.

First, thank you for your help!

It's Windows. I can mount the volume from another PC.

Also the nickname I came up with when I was like 13 and it just kind of stuck. I'm 27 now, guess I should change that.

I don't know. Once you have a nickname on the internet, you're branded for life.

Or a title like "Belly-button Lint Extraordinaire"... :p
