how to rebuild the 1TB Fusion Drive to recover the missing 500GB space
Note:
This is a follow-up on the question originally posted here.
Issue:
Basically, I have a 1TB Fusion Drive, and there is one 500GB partition (or drive) called Macintosh HD inside it as shown below. 500GB space is missing as the result of deleting a Bootcamp partition previously.
Objective:
So, I want to recover the missing 500GB space and merge it back with the current 500GB Macintosh HD.
What have I tried?
What I tried was described in the original post.
What help do I need?
I want know the exact lines of commands to be used in the Terminal during the Internet Recovery process to rebuild the Fusion Drive as suggested by @Loner T in his post here.
Thank you for your kind help in advance.
