Trouble restoring hard drive space after deleting bootcamp partition I have a problem with my Fusion Drive. I created partition for Bootcamp, then deleted it, then something went wrong. I lost 200 GB of space and I have a trouble restoring it, Fusion Drive capacity should be 1.1 TB not 800 GB. Here is my Mac's diskutil list:  

iMac-Lukasz:~ lukasz$ diskutil list

Any ideas how to restore it to the full size?
The HDD part of your Fusion Drive contains an alien EFI partition:

3:                        EFI NO NAME                 104.9 MB   disk1s3


This second EFI blocks restoring a full sized container:


Get the details: diskutil list
Remove the NO NAME EFI:

diskutil eraseVolume "Free Space" %noformat% /dev/diskXsY #replace with the device node of the NO NAME EFI (in your example disk1s3)

Get the APFS container reference of the APFS container spanning the two physical drives: diskutil ap list. (In your example disk2) 
Resize the container:

diskutil ap resizeContainer containerReferenceDevice 0


with containerReferenceDevice = disk2 this is:

diskutil ap resizeContainer disk2 0
