The problem with fusion drive storage

I tried to set up windows 10 via boot camp .  An error occurred during installation. As a result, my disk is split. Below is the output from terminal

What is the normal actual storage capacity for a 1TB fusion drive? Hi After a failed windows installation using the bootcamp assistant, I have set the partition back to just one again. Now I would like to try to install again, but it seems to me like I'm missing a lot of space after this. Not entirely sure what is normal here, but I have a 1TB fusion drive (2018 iMac). It shows correctly under Fusion drive in Disk Utility: However, when I click into the only child drive, it shows only 774GB. I understand that the system takes some space too, but I was just a bit surprised that it takes as much as 226 GB. Is this normal? If it is, then there is no issue. I just want to make sure there is no "lost disk space" floating around after the failed Bootcamp partitioning. This is what diskutil list gives me: /dev/disk0 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_APFS Container disk2 746.3 GB disk0s2 /dev/disk1 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *28.0 GB disk1 1: EFI EFI 314.6 MB disk1s1 2: Apple_APFS Container disk2 27.7 GB disk1s2 /dev/disk2 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +774.0 GB disk2 Physical Stores disk1s2, disk0s2 1: APFS Volume Macintosh HD - Data 385.9 GB disk2s1 2: APFS Volume Preboot 83.0 MB disk2s2 3: APFS Volume Recovery 528.5 MB disk2s3 4: APFS Volume VM 2.2 GB disk2s4 5: APFS Volume Macintosh HD 11.0 GB disk2s5 (or as image: ) Any qualified feedback appreciated.

Disk Utility unable to resize partition I have an external 4 TB drive with two 2 TB partitions, A and B. I want to resize the partitions so that I have one 3 TB partition and one 1 TB partition. When I try to use the Disk Utility GUI to accomplish this, it shows me I actually have three partitions: Partition A (2 TB) – "You can not remove the first volume on the disk." Partition B (2 TB) – "You cannot remove this volume because the previous volume cannot be resized." Free space (516 MB) When I try to (in a single action) remove the free space, then remove Partition B, then add a new 1 TB partition and resize Partition A to 3 TB, I get the following error: "Running operation 1 of 4: Remove “--”… An internal error has occurred and the disk for one of the specified operations could not be found. This may be a temporary issue, try again. Operation failed…" Similarly, when I just try to remove the free space and Partition B, I get the same error (now when "Running operation 1 of 2"). Any suggestions on what I can do? The result of running "diskutil list" with both partitions mounted is shown below. ("Dan's Carbon Copy Clone" is Partition A and "Data Dump" is Partition B, though I am amenable to deleting whichever partition is required as they are currently exact duplicates of each other.)

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.)

You seem to have external storage connected to the Mac, when installing Windows. Disconnect all external storage during Windows installation, which can be connected after Windows is fully installed.

To get your disk space back, run (assuming the 3TB disk stays disk1)

diskutil eraseVolume free free disk1s6

diskutil eraseVolume free free disk1s5

diskutil eraseVolume free free disk1s4

diskutil eraseVolume free free disk1s3

diskutil apfs resizeContainer disk2 0g

and post the output.

If you need install Windows, reset SMC and NVRAM, before your next attempt.
