Hi,
I have encountered an annoying issue with file copy from a CIFS share to the
same share using Windows.
The issue occurs when using the Win32 CopyFile function, in my case .NET
File.Copy().
The problem also occurs when using the command line 'copy' but not with
copy/paste in the explorer.
The result of the copy is a file with the same length as the source but the
content is all null bytes.
The issue only occurs when the source and destination is on the same share.
Copying between shares on different machines (Windows Server <-> OpenSolaris,
OpenSolaris <-> OpenSolaris) works.
I've reproduced the issue on OpenSolaris 2009.6 (111 and 118) and Nexenta Core
(104) using Windows Vista, Windows 7 and Windows Server 2008 as clients.
Windows XP as client works and doing the same thing on a Windows share also
works.
Here's how I reproduce the issue:
C:\>net use z: \\host\share
The command completed successfully.
C:\>z:
Z:\>echo hello> file1
Z:\>type file1
hello
Z:\>copy file1 file2
1 file(s) copied.
Z:\>type file2
Z:\>dir file*
2009-08-22 12:31 7 file2
2009-08-22 12:31 7 file1
2 File(s) 14 bytes
Hexdump:
file1: 68 65 6c 6c 6f 0d 0a |hello..|
file2: 00 00 00 00 00 00 00 |.......|
I can't find anything regarding this issue on the net and I've tried everything
I can think of...
Any ideas?
