FspFileSystemCreate() returns STATUS_OBJECT_NAME_NOT_FOUND (C0000034)

[turner]

Hello, after I restarted my Windows 10 the FspFileSystemCreate() function now returns STATUS_OBJECT_NAME_NOT_FOUND (C0000034) on every single call. Before the restart it worked as expected. Any ideas why could this be happening?

Oh and I forgot to add, i tried restarting the driver via:

D:\WinFsp\bin>fsptool-x64.exe unload
D:\WinFsp\bin>fsptool-x64.exe load

and also by restarting the WinFsp.Launcher service

In both cases it did nothing

Hello,

If you're using a folder mount point, did you check if the mount point folder is still there, but inaccessible?

This happened to me and my solution was to detect when the folder is left over (due to a crash or computer restart) and delete the broken mount point before mounting WinFsp.

I am using a drive mount and if i go to explorer -> This PC i dont see my WinFsp drive which would usually be X: or Z:, however i do see them in the Quick Access section: 

But if i try to click on them nothing happens, i just assume they are there because explorer detects me going there often?

Also me calling the FspFileSystemCreate() function is done before calling FspFileSystemSetMountPoint() so does the mount point in this case even matter?

This is a peculiar error. FspFileSystemCreate may fail with STATUS_NO_SUCH_DEVICE if it cannot find the driver. A STATUS_OBJECT_NAME_NOT_FOUND should not be possible.

 

It would be very helpful if we found out the exact location that is failing. Are you able to debug the the file system creation process using symbols from https://github.com/winfsp/winfsp.sym?

 

Thanks.

 

Bill
