I have a NAS running FreeBSD/FreeNas 8.0.4 When I copy files from a windows system to it via SMB/CIFS normally (explorer/copy) it all goes fine. User can create/delete/update files

When i attempt the same thing with Robocopy. I get either of 2 errors, depending on command.

robocopy .\ \\freenas\temp *.* /FFT
2011/06/15 21:17:58 ERROR 5 (0x00000005) Time-Stamping Destination File \\freenas\temp\test.txt
Access is denied.

robocopy .\ \\freenas\temp *.* /COPY:DA
2011/06/15 21:18:08 ERROR 5 (0x00000005) Changing File Attributes \\freenas\temp\
Access is denied.

From the default config, I've set the following in smb.conf

map archive = yes

dos filetimes = yes

Any other clues?

  • Here is the closest solution I've found. A upgrade to ZFS v28 freenas forum Which I'd have to wait to official get into the Freenas release cycle to verify

    For what it's worth, I have the same issue on a CIFS share on FreeNAS 9.1.1. Permissions are rwxrwx--- and my user is member of the group.

Try using /COPY:DT to only copy data and timestamp info, not file attributes. You should probably keep using the /FFT switch too.

  • Still getting timestamp error. I've googled around and it just looks like some samba v timestamp issue??? But it's really hard to pinpoint exactly... Other say just use xcopy (which does work)

I had this problem copying from a Windows Server 2008 R2 machine to a Windows Server 2003 domain controller through an RDP client network share (e.g. \\tsclient\D).

Using an older version of robocopy from the Windows Server 2003 Resource Kit (XP010) worked fine.

  • How do you convert a copy of the older robocopy version?

Try copying over first in restartable mode /Z, then backup mode if that failes /B, so add the parameter /ZB and let us know what happens. It might solve your issue, but no guarantees. I would also be mighty sure you have your permissions and everything kosher.

  • Unfortunately I still get the changing file attributes error with both /Z and /ZB and /B.
