Hi,
I upgraded our FAS2240-2 filer on the weekend to Ontap 8.2. Everything went ok. I was hoping to use SMB 3.0 to store our Hyper-V VMs for out Windows 2012 hosts. I can't seem to create any VMs on the new shares that I set up though. I have CIFS connected to my domain and can browse and create files in any new shares I make. I have given all the Hyper-V machine accounts full access to the share. I have tried Unix, NTFS and Mixed permissions on the volumes and shares.
When I just try and make a new VHD on the share I get this error:
New-VHD : Failed to create the virtual hard disk.
The system failed to create '\\obethree\vol_HyperV01\test\test.vhd': The request is not supported. (0x80070032).
'': The filename '\\obethree\vol_HyperV01\test\test.vhd' is reserved for use by Windows. Error: 'The request is not
supported.' (0x80070032). (Virtual Machine ID )
The operation is not supported.
I created a GPO that enabled the HyperV machines to 'Manage auditing and security log' and applied it to the computer accounts for the filer in the domain.
If I try this on a share created on a Windows 2012 server, it works fine.
Interestingly, when I look at 'options' on the filer, I don't see any reference to SMB 3:
obethree> options cifs.smb
cifs.smb2.enable on
cifs.smb2.signing.required off
cifs.smb2_1.branch_cache.enable off
cifs.smb2_1.branch_cache.hash_time_out 3600 (value might be overwritten in takeover)
So have I not enable SMB 3.0 just by installing Ontap 8.2 or is this some sort of permissions issue?
Many thanks,
Tom
Solved! See The Solution
You didn't mention if you're running in 7-Mode or clustered Data ONTAP mode.
SMB 3.0 support is only available in clustered Data ONTAP 8.2.

Hi Andris,
It is running in 7-Mode. I guess that explains it, thank you.
Cheers

Hi Andris:
Where I can find the document that about SMB 3.0 support only Cluster Ontap 8.2?
Or which document will decribe that?
I need the document to give my customer,
Thank you!
Yes, those sources would work.
If you need a nice presentation to show the customer, look for "Windows File Services in Clustered Data ONTAP 8.2-Customer Presentation" on the NetApp Field Portal.
What do you suggest for customers who are using 7-mode and want to use SMB 3.0 shares to host Hyper-v VMs? Is it appropriate to create a Windows Server 2012 R2 scale-out file server cluster backed by CSV attached to the filer(s)? Is that going to offer poor performance because of all the I/O stacks it's having to traverse?
Hi Gents,
I've found this documentation offical from netapp
https://kb.netapp.com/support/s/article/what-is-the-default-negotiated-smb-version-with-various-versions-of-data-ontap-and-windows-clients?language=en...
Hope it helps,
Best regards,
