Cannot repair fusion drive

We just bought a 2017 iMac with fusion drive. It seems I have the problem where the drive shows up as two separate drives. I am running Mojave. I have tried booting in to recovery and running the diskutil resetFusion command and I get an error stating, “Your computer must have exactly 1 solid-state and 1 rotational disk drive”. I’m not sure where to go from here. The disks that show up are: rotational (disk0) and MACintosh (disk1s2), Untitled (disk3s1). Just looking for some help getting things running correctly.

Hello Matt_SD,

Thanks for reaching out to Apple Support Communities. I understand you are having an issue with the Fusion Drive on your Mac. I'm happy to help you find a resolution.

If your Fusion Drive appears as two drives instead of one, it's no longer working as a Fusion Drive. It looks like you may have already followed all the steps listed in:
