Hello (Storage Insights) Team, @Sushil Sharma

I have a question about the unmapped capacity figures in SI Pro.

When I look at the storage system properties, I get a figure of 12TiB of unmapped capacity.

This figure also matches what I see on the Flash system.

When I then look at the properties of the (only) pool in the system, I get a (very large) figure of 5220TiB.

I can't make sense of this. If I add up the capacities of the existing unmapped vdisks (including the change-vols), I don't get anywhere near this high number.

Can someone explain this to me please?

Pool Properties:

We have multiple SI instances, and I'm also seeing this in another environment.

Thanks.
