          You'll want to shrink the filesystem - any kind of logical volume management or similar containers - then the image. I'm going to assume you're talking about a RAW disk image.



          Steps at a glance:




          • Ensure the image is not being accessed (ex: lsof)

          • Shrink the filesystem (ex: resize2fs)

          • Perform a filesystem check (ex: fsck)

          • Shrink any LVM or other kind of containers (if needed)

          • Shrink the disk image (ex: dd to a new image with skip or use qemu-img)

          • Fsck again, test that it works!


          Alternative:




          • Create a new image and copy the data / MBR / etc. over.

          • Clone the image with something like partclone

            NOTE Make a backup, anything can go wrong ...
            I ran all those as root :




            1. bind a loop device to the image: losetup /dev/loop10 $image_file

            2. refresh partitions: partprobe /dev/loop10

            3. adjust partition size: gparted /dev/loop10

            4. undo the loop: losetup -d /dev/loop10

            5. remove unwanted space: truncate -s -${SIZE}G $image_file (you might want to calculate the exact size based on values from fdisk/cfdisk * sector size)

              You'll want to shrink the filesystem - any kind of logical volume management or similar containers - then the image. I'm going to assume you're talking about a RAW disk image.



              Steps at a glance:




              • Ensure the image is not being accessed (ex: lsof)

              • Shrink the filesystem (ex: resize2fs)

              • Perform a filesystem check (ex: fsck)

              • Shrink any LVM or other kind of containers (if needed)

              • Shrink the disk image (ex: dd to a new image with skip or use qemu-img)

              • Fsck again, test that it works!


              Alternative:




              • Create a new image and copy the data / MBR / etc. over.

              • Clone the image with something like partclone
