Open Media Vault VM crashing when copying between CIFS shares


Feb 22, 2020
Good morning all! I'm having problems with an Open Media Vault VM on Proxmox and am seeking advice on how to debug the issue. I have an OMV 6.0.latest VM running on Proxmox 7.4-3. The OMV VM is configured to serve up multiple CIFS shares. The harddisks behind the shares appear to be working.

Here's the situation. I can successfully copy large files to/from the CIFS shares over my network from both OSX and Ubuntu hosts. However, when I try to copy between two CIFS shares, OMV consistently crashes after a few hundred MB have been transferred.

I've tried posting this problem on the OMV forum, but so far no one has been able to help me. So, I'm wondering if it might be a problem related to my VM configuration or Proxmox itself. I'm attaching my configuration.

Any suggestions would be appreciated.
