Deleted Bootcamp partition and it just disappeared. Nothing to merge with OSX partition

bootcampdisk-utilitypartition

I had Windows 10 Bootcamp on my MacBook Pro 15" 2015. I just tried to remove the Bootcamp with Bootcamp assistant by clicking "restore" and it gave me an error saying "The disk cannot be partitioned or restored to a single partition."

So I followed instructions given by this answer and I deleted the Bootcamp partition using Disk Utility.

The partition was successfully deleted and there was 200GB of unused space. I tried to merge it with my OSX partition and it gave me an error. Forgot what type of error exactly, something about one of partitions being broken (wrong amount of blocks or something?)

Now the problem is that the 200GB of unused space (previously used by Bootcamp) just disappeared. Nowhere to be seen.

What can I do to fix this? How can I get my OSX partition back to the original 500GB?

diskutil list

diskutil cs list

No CoreStorage logical volume groups found

sudo fdisk /dev/disk0

sudo gpt -r show /dev/disk0

You show in your posted image that the partition is encrypted. I was unaware a partition could be encrypted without using core storage. Anyway, I believe the correct command to fix your drive is given below.

sudo  diskutil  resizevolume  /dev/disk0s2  R

The command should move /dev/disk0s3 to the bottom of disk0 while resizing /dev/disk0s2 to maximum size. I am not sure if the sudo prefix is required.

I think I messed up the Fusion Drive on the 1TB iMac (with BootCamp)

Theoretically everything is fine with your Fusion Drive. Fusion Drives look like this. Disk0 is your SSD with 121 GB and disk1 is your HDD with ~1 TB (~1.121 TB summed up).

The larger parts of your SSD (disk0s2) and your HDD (disk1s2) are pooled to a CoreStorage LVG (Fusion Drive: disk3) with a size of 967.8 GB. The rest is reserved for EFIs, a Recovery HD (alltogether ~1.3 GB) and your old Windows partition - now probably free space (~152 GB).

The logical volume 'Macintosh HD' (967.8 GB) spans disk0s2 and disk1s2. This is the first 'Macintosh HD' in picture 1. The volume 'Macintosh HD' - it's the one visible on the desktop - should ideally also have about 967.8 GB. This is the second 'Macintosh HD' in picture 1.
In fact it has only 852.67 GB (see picture 3).

In the second picture the logical volume 'Macintosh HD' is the first listed in black, the volume 'Macintosh HD' is the second listed in black, the other two 'Macintosh HD's listed in grey are the parts of your SSD and HDD dedicated to the logical volume 'Macintosh HD'.

In my opinion something went wrong after deleting various partitions with the Bootcamp Assistant/Disk Utility or in Windows.

Preparation:

Detach any external drive (especially your external Time Machine backup drive)
Restart to Internet Recovery Mode by pressing alt cmd R at startup.
The prerequisites are the latest firmware update installed, either ethernet or WLAN (WPA/WPA2) and a router with DHCP activated.
On a 50 Mbps-line it takes about 4 min (presenting a small animated globe) to boot into a recovery netboot image which usually is loaded from an apple/akamai server.

I recommend ethernet because it's more reliable. If you are restricted to WIFI and the boot process fails, just restart your Mac until you succeed booting.

Alternatively you may start from a bootable installer thumb drive (preferably Mavericks or Yosemite) or a thumb drive containing a full system (preferably Mavericks or Yosemite).

Now you may either repair CoreStorage or rebuild your Fusion Drive:

'Repair CoreStorage' (not recommended):

First i would try to check the volume 'Macintosh HD' with Disk Utility. If the volume is corrupted consider a reinstall of Mac OS X.
If the volume is ok quit Disk Utility
Open Terminal and enter diskutil unmountDisk /dev/LVIdentifier and both diskutil unmountDisk /dev/DiskContainingApple_CoreStorageIdentifier
In your case: first diskutil unmountDisk /dev/disk3 then diskutil unmountDisk /dev/disk0 and diskutil unmountDisk /dev/disk1
remove the EFI NO NAME partition with gpt remove -i IndexNumberOfEFINoName DiskIdentifier:
gpt remove -i 4 disk1
Remount the CoreStorage disks and then the Logical Volume:
In your case: first diskutil mountDisk /dev/disk0 and diskutil mountDisk /dev/disk1 and then diskutil mount /dev/disk3.

enter gpt -r -vvv show /dev/diskIdentfierOfApple_CoreStorage to get infos of your HDD CoreStorage disk.
In your case: gpt -r -vvv show /dev/disk1
It should look like this:

-bash-3.2# gpt -r -vvv show /dev/disk1
gpt show: /dev/disk1: mediasize=1000204886016; sectorsize=512;         blocks=1953525168
gpt show: /dev/disk1: PMBR at sector 0

The free space on your HDD has 280634887 blocks. Please calculate the biggest block number dividable through 8. That's 280634880 blocks (á 512 bytes) which equals 143685058560 B or ~143.7 GB. Add the size of your HDD CoreStorage Physical Volume (852666400768 B) The result is 143685058560 B + 852666400768 B = 996351459328 B
Resize your HDD CoreStorage physical volume with diskutil cs resizeDisk HDDPVUUID newsize
In your case: diskutil cs resizeDisk 93892BE8-2B7F-4ABD-A4C3-984495DCD98D 996351459328b
Calculate the maximal size of your CoreStorage Logical Volume in diskutil cs list: (size disk0s2) + (size disk1s2) In your case that's 120988852224 B + 996351459328 B = 1117340311552 B. That should be the size of your refreshed Logical Volume Group.
Resize your Logical Volume with diskutil cs resizeVolume LVUUID LVGSize-128 MB In your case that's diskutil cs resizeVolume D237FFDC-7DA4-41D7-AC13-4CC7E5E8C0A0 1117212311552b. If you get an error (There is not enough free space...) choose a smaller size like 1117148311552b.
Quit Terminal and open Disk Utility.
Check your expanded CoreStorage Volume for errors.
Quit Disk Utility, choose your CS volume as startup disk and restart your Mac

'Rebuild Fusion Drive' (recommended if you have a Time Machine backup)

Booted to Internet Recovery Mode open Utilities → Terminal in the menubar and enter:
diskutil cs list to get the CoreStorage listing.
Copy the Logical Volume UUID, it's the fifth listed.
Now delete the Logical Volume with diskutil cs deleteVolume LVUUID.
In your case: diskutil cs deleteVolume D237FFDC-7DA4-41D7-AC13-4CC7E5E8C0A0.
Copy the Logical Volume Group UUID, it's the first listed in the listing of diskutil cs list.
Then delete the Logical Volume Group with diskutil cs delete LVGUUID.
In your case: diskutil cs delete 1EFE58BC-3613-44C4-86EE-D816F3B66E3E
Enter exit and quit 'Terminal'
Open 'Disk Utility'. Enter 'Ignore' if you are asked to fix the drives.
Choose your SSD and partition it: 1 Partition Mac OS X Extended (Journaled), hit the Options button and choose GUID Partiton table and hit OK and Apply.
Please check that the size is ~121 GB

Example:
Choose your HDD and partition it: 1 Partition Mac OS X Extended (Journaled), hit the Options button and choose GUID Partiton table and hit OK and Apply.
Please check that the size is ~1 TB

Example:
Quit Disk Utility and open Terminal
Enter diskutil list

Example (your disk identifiers and sizes are different of course: Your volume SSD probably has the Identifier disk0s2 and the size 121 GB and your volume HDD probably has the Identifier disk1s2 and the size 1.0 TB):
Enter diskutil cs create "Name" IdentifierSSD IdentifierHDD
In your case probably diskutil cs create "Macintosh HD" disk0s2 disk1s2.

Copy the resulting LVGUUID

Example:
Enter diskutil cs CreateVolume LVGUUID jhfs+ "Macintosh HD" 100%.

Example:
Enter diskutil cs list
Check the size of your Logical Volume. It should have the size ~1.121 TB

Example:
Quit Terminal
Open 'Disk Utility' and check your newly created volume for errors
Quit 'Disk Utility'
Attach your external Time Machine backup drive or check this answer if you use NAS or another network share.
Open 'Restore from Time Machine Backup'
Choose the appropriate Time Machine backup and restore your system
Reboot to your restored system.
Unmount and detach your Time Machine backup drive
Open 'Terminal' and enter 'diskutil list'
Check if your 'Recovery HD' is listed.
If your 'Recovery HD' is missing, usually reinstalling your current system with the latest available system installer (e.g. 'Install OS X Mavericks (10.9.5)' if Mavericks is currently installed) will recreate it without loosing any data. AFAIK Recovery Partition Creator 3.8 will NOT create a Recovery HD on CoreStorage volumes.
After reinstalling the system with the latest available system installer open App Store and install the latest security fixes.

MacOS – How to add free space to a Logical Volume Group? (Resizing Partitions)

You can't move the start block (=380677208 for LVG2 or "Macintosh HD 2" in your case) of a CoreStorage Volume (Group) non-destructively. The same is valid for non-CoreStorage partitions with on-board tools. AFAIK for the latter only iPartition and gparted work. Therefore you can't easily reclaim empty space with a lower start block and an arbitrary size and add it contiguously to existing CoreStorage or non-CoreStorage volumes.

Or with other words: You can expand volumes (CoreStorage or non-CoreStorage) from the ending block to higher block numbers but not from the starting block to lower ones.

You have 2 options though:

Recreating a larger second CoreStorage volume
Creating a new partition in the empty space and adding it as physical volume to your second Logical Volume Group. This will scatter your second Logical Volume Group over several Physical Volumes (PV2 & PV3 - the latter build in the empty space) on the same drive but might be unavoidable if another partition like your Recovery HD or a Data volume exists between LVG1 and immediately before PV2.

Both methods require you to backup/move the content of the second Logical Volume to another volume and its deletion afterwards.

For both methods force-backup all your data.

Then boot to an external thumb drive containing a bootable system or to Internet Recovery Mode (hit altcmdR immediately after the start-up chime)

open Terminal.app in the menubar (Utilities/Terminal)
enter diskutil cs list and diskutil list
enter diskutil cs deleteVolume LV2UUID to delete the second Logical Volume
in your case diskutil cs deleteVolume 976CA58C-E8FF-492A-9968-6FEF64C58A31

Now the 2 different methods divert:

Recreating a larger second CoreStorage volume (recommended):

enter diskutil cs delete LVG2UUID to delete the second Logical Volume Group
in your case diskutil cs delete 4793C4C8-0F56-4673-A2B6-98B15403CD33
Your second Logical Volume Group will be converted to a classical volume with the name "Untitled". This will take some time because it also has to be decrypted.
If you enter diskutil cs list repeatedly you will see the progress of the decryption task (in %).

after the conversion completed enter sudo gpt -r -vvv show -l /dev/disk0*
you have to enter an admin password then
