Samba server in guest cannot access files via shared folders

[Jürgen Schaumlöffel]

I want to operate a Linux Samba server(guest) on Win7 (host), in which the Samba share point-to sharedFolder (vboxsf) on the host NTFS-Filesystem.

Win7Host: C:\myShare <-- vboxsf auto-mount --> LinuxGuest: /media/sf_myShare, Samba: [MYSHARE] path = /media/sf_myShare

If folder/files are copied under Win7 into C:\myShare, it happens, that copied folders/ files aren't visible thru Samba access. On the other hand - if I make the copy via Samba-share, it happens sometimes that particular files couldn't written to the share. In both cases on Linux command line a 'ls' shows folder/ file name(s), but no attributes, only ?????????????. Reason unknown.

Oracle VBox 4.1.6, host: Windows 7 SP1, guest: 3.5.1-1-ARCH Linux, Samba 3.6.1 Because of similar bug tickets (#9952, #9789, #9887) I tested too with VBox 4.0.12, negativ - same error.

I find a way to reproduce this behavior anytime:
1. Win7 robocopy: C:\folderX to C:\myShare
2. windiff: compare C:\folderX with \linuxguest\MYSHARE\folderX --- OKAY
3. rename \linuxguest\MYSHARE\folderX to folderY
4. robocopy again C:\folderX to C:\myShare
5. windiff: compare source\folderX with \linuxguest\MYSHARE\folderX --- ERROR
6. linux, ls shows /media/sf_myShare/folderX ????????????

I don't see this problem, when I rename the folder under Win7 directly - only by renaming over Samba.

This might be a duplicate of #9878. I won't mark it as such yet though.

You might want to give this pre-release 4.1 Additions build (usual disclaimer applies) a try:

I tested VBoxGuestAdditions_r75555(=4.1.9) with

host:Win7SP1(host)--VBox4.0.12-GuestAdd-4.1.9--guest:3.5.1-1-ARCH Linux
host:WinXPSp3(host)--VBox4.1.6-GuestAdd-4.1.9--guest:3.5.1-1-ARCH Linux

I have deactivated the samba server on linux guest, to consider only the vbox sharedfolder behavior.

In both environments, I can reproduce the ??????????? situation via:

1. on Windows-host: Copy folderX (with subfolders) to C:\myShare
   
2. on Windows-host: rename folderX to folderY
   
3. on Linux-guest: ls -lisa /media/sf_myShare/folderY --- OKAY
   
4. on Linux-guest: rename (~ mv) folderY to folderZ
   
5. on Windows-host: working on folderZ and subfolders --- OKAY
   
6. on linux-guest: ls -lisa /media/sf_myShare/folderZ --- Error
   

Subfolder is not accessible, its Attributes shown as ???????????
