[lustre-discuss] Luster access from windows

[Todd, Allen]

How you do it is a matter of what scale and performance you are trying to achieve.  I can confirm that the vm method works and has the benefit of scaling out the number of lustre clients with the number of windows servers, but to perform well takes a non-trivial amount of tuning. We found the compute resources lost to SMB and virtualization on each node more or less equal to a dedicated SMB/lustre gateway for the same amount of bandwidth.   For casual, non compute cluster access, just running samba on a linux client works fine.  For a high availability solution, where you need to support read/write from windows clients with guaranteed data consistency, CTDB works fine at smaller scales (4 or fewer SMB servers).

Feel free to follow up with more specifics about your use case,

Allen

Hi Parag,

I attended a presentation at LUG 2013 that talked about sharing Lustre with Windows. The method was:
 + On your 'Windows' machine, first install Linux with the Lustre client, and mount the Lustre file system.
 + Next, install Windows with KVM on the Lustre client, and use the local Lustre mount from Windows.

The presentation is here:

If a video is available, there might be more discussion you can access with that...

best regards,
Richard
