What Should I Do With The Fusion Drive When I Factory Reset My Mac?

Hi, I have an iMac 2015 with a 2 TB Fusion Drive. My Mac has started to slow considerably and I would like to reset/reinstall MojaveHi there, you don't need to do anything with the Fusion Drive when you reset or reinstall your iMac, just boot into macOS Recovery Mode for the reinstallation task. ' If you erase your drives separately then you ought to combine your drivers before the reinstallation. Below are the command lines to create a fusion drive: To find out physical storage volumes: diskutil list To create Fusion drive: diskutil coreStorage create "Macintosh HD” /dev/disk0 /dev/ and start fresh. The question I have is: when I erase the HD do I need to do anything additional to take into account the 128 GB Fusion Drive? Or does the installer just count the volumes as the same?
