Problem creating an NFS shared folder into an WinFsp mount point

[Eric Vial]

Hi,

On Windows Server, I'm trying to create an NFS shared folder inside a WinFSP mount point but I got the following error message from the Windows creation wizard: "The file system in the target volume is not supported by NFS". The same test using memfs produces the same error.

Creating an SMB shared folder inside memfs works fine. Is it supposed to work as well with NFS?

Cheers

Hello, Eric:

 

WinFsp is specifically tested for this scenario for SMB shares. Unfortunately there is no such testing for NFS shares.

 

It is likely that NFS exports require something from the underlying file system that is not being fulfilled:

 

• It may be as simple as checking whether the file system name is “NTFS” (I recommend changing your file system’s name to “NTFS” and seeing if that works).

 

• It may interrogate the file system for a specific IOCTL/FSCTL code that is not currently implemented by WinFsp. Consider using FileSpy (http://www.zezula.net/en/tools/filespy.html) to see the IRP’s sent to the file system.

 

• It may be more complicated than that.

 

Consider opening an issue for this in the GitHub repository. Please include detailed steps to reproduce the issue.
