Incorrect Drive size after deleting Bootcamp

I have a 3.2 TB Fusion drive but my iMac is only reporting 2.92 TB under Catalina. This happened after I deleted my 200 GB Bootcamp partition using Bootcamp Utility. I was able to delete the Bootcamp partition but it gave me an error and I did not get back the 200 gb.


I tried to resize the drive using diskutil apfs resizeContainer disk2 0g but only received an error:


Error: -69606: A problem occurred while resizing APFS Container structures


diskutil list gives me this:


/dev/disk0 (internal, physical):


   #:                       TYPE NAME                    SIZE       IDENTIFIER


   0:      GUID_partition_scheme                        *121.3 GB   disk0

   2:                 Apple_APFS Container disk2         121.1 GB   disk0s2

Your APFS Container for the Fusion drive has corruption. Your Fusion drive is working, but the quickest fix to address the corruption is to rebuild the Fusion drive and restore the backup.


You need to rebuild the Fusion drive in Internet Recovery, not Local Recovery.

Ok, I can do that, but it does show that I have a 3.12 TB fusion drive under "About this Mac."


The instructions your referred to says If you see a drive labeled Fusion Drive, your Fusion Drive is working and this article doesn't apply to you.


Does that matter?
