So recently I was hoping to use BootCamp to run some Windows only applications, but as of today. I realise my fusion drive's file system/structure seems to be abnormal. Any help on fixing my weird file system? (I am aware of the 700GB free space, I can't seem to be able to get disk0 to re-adopt it.)

That is a mess. I cannot tell whether the Fusion Drive is still intact or not. If you don't have a current backup, then make a backup immediately so you don't lose any data.


After getting a good backup, then you should start over by recreating the Fusion Drive setup. It is possible you may first need to break the Fusion Drive if macOS still sees it before you can use the instructions to reset or create the Fusion Drive.

After resetting the Fusion Drive and reinstalling macOS, then you will need to use BootCamp Assistant to modify to resize the partitions to create a new partition for Windows and to install Windows.

FYI, I recommend creating a bootable macOS USB installer if you can still boot into macOS so you have access to more options in case you have issues with Internet Recovery Mode.
