The answer in this specific situation is always going to be “yes”, so the yes command is piped into the command to automatically provide a “yes” answer to the confirmation dialog. However, repairDisk asks for a Yes/No confirmation before running. To automate the process, I wrote a script to run the repairDisk command. Once the diskutil repairDisk command had been run to fix the partition map, I verified that the following command could now resize the partition without problems: You should use "diskutil repairDisk" and then repeat this command.Īfter some testing, the following command resolved the problem I was seeing: Your partition map does not use the entire space of your whole-disk.
After some discussion with Nick Cobb in the MacAdmins Slack, I noticed this section of the error message I had received: Unable to extend a partition using the guest Disk Utility after extending disk of a virtual machine running Mac OS X (2069255)īoth posts confirmed that this was a known issue, but neither offered viable fixes for the problem I was seeing.My research on this problem turned up the following links:
How to fix this? For more details, see below the jump. However, this time the re-sizing process failed and the following error was displayed: Normally, this command is able to do a live re-sizing of the boot partition to use all available unallocated space. Resize the new VM to the desired size using VMware’s vmkfstools utility.Īfter logging in, I ran the following command to enable macOS to recognize and use the unallocated space from the VM resizing: Set up a new VM, using copies of uploaded VMDK files for the VM boot disk.ĥ. Upload the VMDK files to a convenient location on my ESXi serverĤ. Sudo vfuse -i /path/to/autodmg_created_disk_image_here -esxģ. Use vfuse to create VMDK files using a command similar to the one shown below: For these VMs, I was creating VMDK files from AutoDMG-generated disk images, using vfuse to convert the disk image into a VM with ESXi-compatible VMDK disk image files.Ģ. I went into Terminal and brought up diskutil list.As part of working on a project recently, I ran into an unexpected problem with ESXi-hosted Mac VMs. Note: Ensure that you have enough free space available on the physical disk to perform the operation. Use the slider to adjust the size of the virtual disk. Go to Fusion Menu > Virtual Machine > Settings Click Hard Disk (s). I cannot resize the blue area for some reason, but I can highlight the "Free Space" area and delete it, which then makes the desired effect happen:Ĭlicking "Apply" leads to the following error.īack to square 1. Select the virtual machine in the Virtual Machine Library. I launched and went to Disk Utility and see this It told me to then handle the partitions for it to take effect inside macOS. I want to expand the disk space, so I went into VMware settings and expanded disk capacity from 40GB to 80GB.
