Hi Stefan,

I haven't seen a response, so I'm going to consider this issue closed. I'm guessing you may be on vacation since it's the holiday season. If that's the case, just send me a response to my query below, and we can pick up where we left off.

Hi Stefan,

The Witness protocol is an essential service for highly available shares. Are there other uses of the SMB2_SHARE_CAP_SCALEOUT capability that you might expect to see? What else do you think it might be used for?

Hi Jeff,

> I'm looking into your question on:
> Question 7:
> The above section is the only place in the whole documentation that references SMB2_SHARE_CAP_SCALEOUT, is that really correct?
>

My assumption is that section '3.2.4.27 Application Notifies Offline Status of a Server' is only triggered when an witness AsyncNotify reponse comes in.

That would mean SMB2_SHARE_CAP_SCALEOUT would only have any meaning if witness is in use and I'm sceptical that this is really the case...

Thanks!
