For me, the dashboard is a way to quickly get an overview of right and wrong. Green/blue is fine and orange/red needs attention.
Currently, shares outside the parity protection but in a redundant pool are displayed in orange, making it appear in the dashboard as if they are at risk.
My proposal:
Shares inside parity protection: Green
Shares inside protected pool: blue
(Mirror, RaidZ)
Shares on single pool disk or unprotected array: Orange
Maybe I'm overlooking something, this won't work for other situations, but in my situation it would be very useful.
