Mac OS X Server 10.3 or later: Issues when saving disk image to local volume

If you save a disk image created in Network Image Utility (Mac OS X 10.3) or System Image Utility (Mac OS X 10.4) to the startup volume, the save process may pause for an extended time and ultimately stop. Cache files that get created when you save the disk image to your startup volume may cause your available disk space to temporarily exceed the space available—sometimes regardless of startup volume size.

To resolve the issue:

  1. Open the Network Image Utility or System Image Utility.
  2. Configure the image name, type, installation options, disk image source, and any other options you wish.
  3. When you're ready to create the disk image, click Create.
  4. When prompted to save the disk image, choose a volume other than the startup volume.
