restore missing space on fusion drive
how can I recover the missing 200gb on my fusion drive. Tried disk utility from the internet recovery, but it won’t let me find that space.Hi darthdubs,
The image provided does not give us a full understanding of your current configuration. See the following article for guidance with partitioning.

https://support.apple.com/kb/PH22240
If you are unable to resolve the issue using Disk Utility, try the following steps to resolve your issue. Please note these actions will permanently delete all data stored on the drives that make up your Fusion Drive.
Back up your Mac

Boot to macOS Recovery

Open Terminal
When you see the macOS Utilities window, choose Utilities > Terminal from the menu bar. Type the following commands, pressing return after each line.
diskutil list internal
Terminal displays a table of data about your drives. In the IDENTIFIER column, find the identifier for each of the two internal, physical drives that make up your Fusion Drive. Usually the identifiers are disk0 and disk1. One of them should be 128GB or less in size. The other at least 1TB in size.
diskutil unmountDisk disk0
diskutil unmountDisk disk1
diskutil eraseDisk JHFS+ SSD disk0
diskutil eraseDisk JHFS+ HDD disk1
diskutil cs create "Fusion Drive" disk0 disk1
diskutil cs createVolume "Fusion Drive" JHFS+ "Macintosh HD" 100%
Reinstall macOS
Quit Terminal to return to the macOS Utilities window. Choose Reinstall macOS, then click Continue to begin reinstalling the Mac operating system. Your Mac automatically restarts from your Fusion Drive when done.
All the best.
