Oh my, guess what?! After I upgraded to 9.1.1 last night. The graphs mostly appear to be correct except for 2 of them.
Here's a funny potential bug I found though.
As you can see, the highlighted one is the ONLY one that's a different size from the rest.
Ironically enough, that number is probably the most correct one and all the 5.4's are wrong.
Someone correct me if I'm wrong, but I have 4 x 3TB drives in RAIDZ1. So it should give me around 9 TB minus swap, etc... so 7.7 sounds about right. Yet, it only appears on one data set and it's not even the top data set...
