Not able to mount Fuse Drive on a Mapped Network Drive in Windows #33

Closed mohankumarv2005 closed 4 years ago

mohankumarv2005 commented 5 years ago

I have a mapped network drive (R:) which is pointing one of the folder on the network E.g. "\server-share\files". When I try to mount FUSE drive to let's say "R:\Fuse" I get below error "Cannot set WinFsp-FUSE file system mount point".

However, I am able to mount Fuse to Local Drive like "C:\Fuse". I have ensured "Fuse" folder is not present.

Any idea on this issue?

Can you please post the full FUSE command line that you use to mount the file system (i.e. the arguments to host.Mount)?

Keep in mind you cannot mount a "network" file system to a directory. Only "disk" file systems can be mounted on directories.

Sure, here it is:

options := []string{"-o", "volname=Altair", "-o", "uid=-1", "-o", "gid=-1"} host.Mount("R:\Fuse", options)

Note: The directory "Fuse" do not exist on R:

In order to mount on a directory, WinFsp must be able to set a "reparse point" on the (newly created) directory.

This is done in the WinFsp internal call FspFileSystemSetMountPoint_Directory. There are a few reasons why this may fail, but I am suspecting that the problem is that the "reparse point" fails on the network drive.

Is the network drive on a Windows server? For example, I believe there are some issues with reparse points on Samba shares.

Sorry for delayed response. The Network Server Setup is on Linux (OneFS). So, it is expected to work?

If the server properly supports reparse points (e.g. a Windows server) I believe that it should work.
