iMac HD issue missing space

[Hassan69]

Hi, I have an issue where I have space that I need to reclaim back but there is no identifier showing when I use diskutil as you can see info below. How do I get this back and what easy steps on how to do this. Thanks in advance.

Space to reclaim back is 370.08GB

/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 629.1 GB disk0s2
3: EFI NO NAME 104.9 MB disk0s3
(free space) 370.8 GB -

/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 - +656.8 GB disk2
Physical Stores disk1s2, disk0s2
1: APFS Volume Macintosh HD 9.3 GB disk2s1
2: APFS Snapshot com.apple.os.update-... 9.3 GB disk2s1s1
3: APFS Volume Preboot 1.9 GB disk2s2
4: APFS Volume Recovery 1.2 GB disk2s3
5: APFS Volume Macintosh HD - Data 19.9 GB disk2s4
6: APFS Volume VM 1.1 MB disk2s6

You need to delete

3: EFI NO NAME 104.9 MB disk0s3

And expand

2: Apple_APFS Container disk2 629.1 GB disk0s2

You will have to do this using diskutil, since Disk Utility won't show you the hidden partitions. Make sure you have a backup before doing anything.

Hi, thanks for your reply and I did a backup and reset the Fusion drive and got back all the storage as one.
