How to fix my split Fusion Drive (iMac) using Mojave

[lawful73]

I've tried Apple explanation and it didn't work:



This is what I get using Terminal (no fix at all):



My mistake was to erase all volumes with Disk Utility to perform a fresh install and now I don't know how to fix muy Fusion Drive. Thank in advance for reading my post and for your time.

Do you have a USB boot disk with macOS Mojave on it? If so, use it to completely erase the drive. Reformat it and then reinstall macOS.

Thank you for your answer. I do have it, but I don’t know how to completely erase both drives (SSD and HHD). Thank you.

When you’re in the Disk Utility section, both drives should be selectable. Erase one and then do the other. Erasing instructions are included via the above link. I hope it helps you.
