cannot copy a file (SMBnttrans/SMBntcreateX)

[Jörg Leinhoß]

Hi,

we have the problem, that we cannot copy a file to a samba share while the same file (equal exept filename and timestamp) we can
copy without problem. The share is in use over several month without problems and we use samba over several years and plattforms.
When we try to copy the file (with the windows explorer) a error box "Cannot copy file. File exists." pops up. In the moment of the
copy a 0 byte long file with the same filename is created in the target dir, which cannot overwritten. The file remains as a normale
0 byte file after cancel the copy process.
After the problem occurs (while try to copy the file to the share) then we rename the file, change the permissions or dos
attributes, copying with the windows explorer lokaly - we cannot copy the file into the share anywhere! When we copy the file to
another share and back, then we can copy the file. A nearly equal file (contents, permissions, timestamps, dos attributes) can also
be copied!

I switch the smbd to log level 5 and capture the log while try to copy the file (filename a) without success and copy an equal file
(filename b) with success.
While try to copying file "a" it comes to a SMBnttrans. While copying the file "b" it comes to SMBntcreateX. What means this? Why?

Thanks and Regards,
Joerg Leinhoss
