Confirmed only one in /Library/Filesystems, and none in /System/Library/Filesystems
Executed the steps in the POOL-6x10TB-b/Music child dataset - success! (and the icon has changed to the Apple default)
Now, if I open Music, no duplicates, and no .VolumeIcon.icns on the desktop.
Went one step further & changed the .VolumeIcon.icns in the POOL-6x10TB-b parent, which changed the experience.
If I now open one of the other child datasets (ie. "Other"), I get the icon creation / slide motion of a second matching icon, however if I open either one of the instances, .VolumeIcon.icns does not show up on the desktop (it keeps both instances - ie. nested where one is a sub of the other).
