Q: space gone after failed partitioning process. I lost 500 gb and can't recover it.
Hi, space on my hd has gone after failed partitioning process. I interrupted the process and after that my boot drive lost 500 gb which i wanted to use for boot camp. Now i can't recover it. Used diskutil resize volume, but get error message about wrong size on the cs and advice to do whole repair. : The provided Core Storage logical volume has an incorrect size; you should run whole-disk repair
Please help.
iMac (Retina 5K, 27-inch, Late 2015), OS X El Capitan (10.11.1)

The simplest and safest method to get your disk space back is
1. Backup OSX and all your files - Use Time Machine to back up or restore your Mac - Apple Support .
2. Boot into Internet Recovery (Command+Opt+R) - OS X: About OS X Recovery - Apple Support .
3. Click on Utilties -> Disk Utility and Erase your internal whole disk. This is the outermost Fusion disk. You can also do the same in Utilities -> Terminal using diskutil commands and rebuild the Fusion drive.
4. Restore OSX and your files - Use Time Machine to back up or restore your Mac - Apple Support .
This requires a separate external disk which can accommodate TM backup - Backup disks you can use with Time Machine - Apple Support .
