    How safe is it to delete the CoreStorage Logical Volume Group? Will all the data on the harddrive stay there?

    And can I make a new CoreStorage Logical Volume Group for my harddrive and Fusion's SSD

    Thanks in advance!

    Since nobody reacts to my question, I started trying out things for myself. And after some searching, I completely reinstalled my mac with succes.

    Here's what I concluded , maybe for other people with this problem ;

    - Yes you can delete the CoreStorage (logical) Volume Group
    - And, yes, you can re-enable the fusion drive. (CoreStorage (logical) Volume Group)
    - Not possible when running OS X, you need to make a separate Recovery USB to load the recovery mode (This is deleted when you delete the all the CoreStorage)
    - Simple walktrough on how to delete CoreStorage (split the Fusion Drive from the normal HDD)
    - Re-enable the Fusion Drive
