Can't rescue original disk size (Sierra)

[Wowzera]

Hello,

I recently deleted a bootcamp partition in my drive, but I can not rescue the size of my drive.
I have a MPB 2015 128GB. But it is currently showing only 83GB of disk space.
Can anyone help me? I have no clue what happened here.

Run "First Aid" on the volume group using Disk Utility, you may also need to force Spotlight to reindex as well...

Ok, just did it and didnt change a thing. Disk utility showed that my disk is ok, nothing wrong.

You need to use the Terminal to solve this issue.

First, make sure to have a full backup of your machine (Time machine, clone)

Then in Terminal, paste this :

diskutil cs resizeStack F753BED7-78F3-43D4-9A8F-3920722FB6E2 0b

Hit Enter.

This command ask to extend the core storage to the maximum space available (0b left).

You should see this in the Terminal :

Thanks for your help, but it didn't solve the issue. Any clue? This is driving me crazy.

The command failed because of the Apple_KernelCoreDump partition : there is no "free" space available "underneath" the Recovery partition.

Do you know why you have this partition ?
Is your Mac a corporate machine, or did you get help from Apple assistance, or other reason ?

No, I dont know.
My mac is a personal machine and I didnt get help from Apple or another reason.
All I did was remove the Bootcamp Partition, but the disk space didnt return to my main drive and neither is listed as available in Disk Utility, its simple "gone".

 

[Bruno09]

The command resizeStack is the right one to solve your issue, however it will only work if there is "nothing" underneath the Recovery partition.

I think there are three ways to solve your problem :

1. delete the Apple_KernelCoreDump partition, then use the resizeStack command

or

2. revert the core storage, then use Disk Utility to delete the Apple_KernelCoreDump partition and expand the Macintosh HD partition to the maximum space available.

or

3. clone your Macintosh HD partition to an external hard drive (Carbon Copy Cloner, 30 days free demo)
Boot from this clone, erase your internal disk, then clone your clone to the internal drive.
(good solution without using the Terminal)

I am not a Terminal guru by any way, therefore I would prefer if someone else with good knowledge came to help you on this...

Please post the output of this command : diskutil cs list

Isn't kernel core dump taking only 655MB?

Yes, but the resizeStack command can only work if there is nothing underneath the Recovery partition in the output of the diskutil list command.

If you want to solve the problem without using the Terminal, use the #3. option (clone, format the internal drive, clone back).

 

[Audit13]

On a PC, the windows installation process creates a recovery partition that is protected and difficult to remove. The same appears to have happened on your Mac and the simplest way to get all of the space back would be to delete all partitions and reinstall the os or restore a time machine backup.

I have no problem using terminal. But I don't know the commands. I cant remove it using Disk Utility (the core dump partition). Do you know how what I have to do?

 

[Bruno09]

But I don't know the commands.

I don't know them either.

I personally would use the #3 solution.

 

[Fishrrman]

OP:

Look at choice #3 in Bruno's post 8 above.

THIS is your answer.

It involves a little time, but it WILL do the job and do it right.

 

[Wowzera]

I did the choice 3 and it solved the problem. Thanks!!
