Not able to restore my 3TB fusion drive late 2013 iMac
I would suggest following the steps in the answer posted here

Most importantly: diskutil cs create "Macintosh HD" disk0s2 disk1s2

Your diskutil output should look more like this with the "logical volume"

$ diskutil list
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *121.3 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:          Apple_CoreStorage                         121.0 GB   disk0s2
   3:                 Apple_Boot Boot OS X               134.2 MB   disk0s3
/dev/disk1
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *1.0 TB     disk1
   1:                        EFI EFI                     209.7 MB   disk1s1
   2:          Apple_CoreStorage                         999.3 GB   disk1s2
   3:                 Apple_Boot Recovery HD             650.1 MB   disk1s3
/dev/disk2
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:                  Apple_HFS Macintosh HD           *1.1 TB     disk2
                                 Logical Volume on disk0s2, disk1s2
                                 D11BC089-D75D-4239-AB60-4293803F5F6D
                                 Unencrypted Fusion Drive


And Core Storage list like this:

$ diskutil cs list
