Hi,
My understanding of the problem is this, most corruption issues are related to the redirector and oplocking.

You are unable to disable oplocking with SMB2, the only way is to disable SMB2 which forces the server back to SMB1 where you can disable oplocking.

Delayed write caching is the other culprit, which under high load discards edits when the buffers are cleared, but the redirector may also be the root cause.
