Hi:
I have a customer who has contacted Microsoft in regards to some performance issues. MSFT have come back asking if their CIFS storage supports SMB2 Qfid. As far as I can tell, it references the following article:
https://msdn.microsoft.com/en-us/library/cc246504.aspx
MB2_CREATE_QUERY_ON_DISK_ID 0x51466964 | ("QFid") The client is requesting that the server return a 32-byte opaque BLOB that uniquely identifies the file being opened on disk. No data is passed to the server by the client. |
The customer is connecting to NetApp storage (clustered OnTap 8.2.3P6). I am unable to find any references to this anywhere in documentation or the NetApp support site. The only reference I could find was in the file access guide for 7-mode version 7.x in which it simply states it is not supported as they could find no reason for using it. Anyone here have any knowledge of this? Thanks.
