Mojave installer reports "This volume is not a supported Core Storage configuration."

I just tried to update my iMac Retina 5k 27", late 2014 running High Sierra 10.13.6 to Mojave. The installer started, but claimed very soon:

(This volume is not a supported Core Storage configuration.). The configuration is a fusion drive with HFS+ filesystem. Due to a hard disk failure the original harddisk was replaced by a Samsung SSD with 2TB some time ago by an authorized Apple Service Partner near Munich.

I read that fusion drives are supported by Mojave and would be converted to APFS during installation. So I didn't expect any problem here.

Any idea how to proceed from here?

Thanks a lot

Wolfgang

Dear all,

today I created a bootable USB stick of the Mojave installer as described here: How to create a bootable installer for macOS - Apple Support

I booted from the stick and erased the "Macintosh HD" volume from the Disk Utility that was available on the install medium. For the new volume I chose "APFS encrypted" as file system. I did a clean installation of Mojave and then used the migration assistant to restore my software and data from my Time Machine backup.

Worked fine, now I'm running Mojave.

Yours

Wolfgang
