Offline Files

  • Thread starter Thread starter Jeffrey S. Sparks
  • Start date Start date
Funny timing--a developer just asked me to have you run a tool for us to
gather more information. Will you contact me via email? Remove "online" from
my address.
 
To close out this thread, after some investigation we have identified the
reason why Offline Files is failing. After reviewing the trace logs that
Jeffrey sent, our developer concluded that the server never grants an oplock
for the file. Jeff realized that he had disabled oplocks on his server for a
database he was hosting. Offline Files in Windows Vista cannot operate when
oplocks are disabled. Here are the two keys Jeff changed to make this work.

He added this key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MRXSmb\Parameters\
OplocksDisabled REG_DWORD 0

And he changed the following key (was set to 0 on his server)
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
EnableOplocks REG_DWORD 1

These keys are described in more detail at

Hi

My small environment consists of a Windows Vista Ultimate (32bit) DELL
Notebook and a IOMEGA NAS Storage Storcenter. My data is shared on the
IOMEGA Storcenter and syncronized for offline use. I've experienced
the same problem that there are created some tmp files and another
strange thing was, that folders have been displayed twice: Once with
the normal name, second with the 8.3 name. Checking the files online
using WinXP Prof. the state is as assumed: The 8.3 Name is NOT
displayed.

Due to the NAS box doesn*t have registry, I can't enable or disable
oplocks on the "server", which is the nas box.

But it seems for me the syncronisation errors I get can be focused to
this problem. So I disabled oplocks, because this is a single user
environment, because there is no danger, other user could overwrite
opend files.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MRXSmb\Parameters
\
OplocksDisabled REG_DWORD 1

Is there any problem using this option in my environment?

Thanks!

Franz

I forgot something to ask:
Is there a way to check, if the iomega nas storage box handles the
lock mechanism correctly? the nas box represents itself as NT Server
4.9

Thx!
 
Hi Jill!
Thank you very much for this information!
Unfortunatley I can't change this settings, but I'll ask Iomega to
provide a solution!

Thanks!
Franz
