ESXi - Resizing Disk

Wow, I was running in circles. I needed to resize a system disk on
one of my development machines, that running on the HA ESX/Vsphere
cluster. It was "grayed" out, and I could not change it.

It puzzled me, as I've resized dozens of times on other machines.
All my machines were created using the latest VM spec, but yet
no resize. I even pushed the disk back and forth between datastores
and it didnt come back.

What was the problem?

If you resize, you can have no snapshots.

Sure enough, deleted my snapshots, and everything was good.
