I've had a random hang that has occurred about 4 times total when transferring large amount of data from Windows 8.1 or Windows 10 to OMV.
OMV to Windows 8.1 (SMB): No problem!
OMV to Windows 10 (SMB): No problem!
Synology NAS to OMV (NFS): No Problem!
Windows 8.1 (SMB) to OMV: Random Freezes
Windows 10 (SMB) to OMV: Random Freezes
Always the random problem comes when transferring from Windows 8.1/10 to OMV over Samba. Sometimes it finishes the copy okay, sometimes it hangs. Randomly Windows copy progress freezes and OMV becomes unresponsive. Can't access it through the main Web GUI and I have to power it down at the machine with the power button. It does recognize I hit the power button and shuts itself down via software.
The board is new ASRock N3150DC-ITX. New memory (Crucial 8 GB), new SSD (Samsung - Storage/Intel - OS), etc. The fact that the issue is asymmetric (issue is only to machine) and only happens with Samba (NFS is okay) leads me to believe this is a Samba issue. Perhaps either a network driver issue or a Samba issue.
Any ideas on where to begin debugging it? Which logs to look at, ideas to try out? Thanks!
