If I run it from recovery mode, it says it works, but didn't actually work. These are one visible partition: The startup disk must be formatted as a single Mac OS Extended Journaled volume and two invisible partitions: EFI and the recovery partition. Usually it's disk0 - below I assume it's disk0. Use the disk identifier you have found in your environment in the commands below! You also have a CoreStorage volume e. Check its disk identifier also. Below I assume it's disk2.

If you haven't mounted it because you didn't unlock it - if it is encrypted , you don't have to unmount it below. Verify the disk with diskutil verifyDisk disk0 and diskutil verifyVolume disk0s2. If you can't repair the errors add a comment to the answer mentioning the error message s and don't continue with the steps below.

Unmount the logical volume and then the internal disk: Quit Terminal. This errors at unmounting disk0.
