Disk space given back to Mac HD after removing partition, but is not usable This looks similar to some other related questions here, but has some meaningful differences. I thought it was worth a separate question for that reason. 

Like others I had an error while installing Windows 10 with Bootcamp. I had the error where you select the BOOTCAMPdrive and then click "Format," and then the disk is renamed to "Disk 0s5" (or close to that, if I remember correctly) and there is an error when you select it to install Windows 10. 

I then followed the many instructions and exited Boot Camp Assistant, delete the recently created partition, and then started to go through the process again. I went back into Boot Camp Assistant and restored the HD to all being for Mac OSX. There was an error during the process. It said it failed, but the Mac HD then said 839 GB again like it should say. However, the 175 GB I had allocated for Windows in the partition, out of the 839, were not available. So when I go to set up the partition again I only have a total of 60 GB available instead of the 235 GB available like it should say after freeing up the former partition. So the 175 I used for the partition is back on the main disk, but I can't use it for anything, and am not sure how to free it up. 

This is the print out of diskutil cs list:

When I run DaisyDisk it also does not show the 175 GB that I should have reclaimed after deleting the partition as being available. It says I only have 60 GB available out of the 839 GB. 




Since daisydisk agrees with the cs list how can I add ~175 GB to get my fusion drive back to 1 TB total capacity?
As DavidAndersen noted in his above comment, this was me needing to resize the Stack. In hindsight, that should have been more obvious to me as 839 was not the full size of the TB disk. After issuing the diskutil cs resizeStack F3D44897-0134-4C19-871A-72E258AECDA8 0 command the last volume is at 1 TB.
