So I have a disk image created by running
dd and copying a full hard-drive (~ 67GB). My end goal is to get this image from 70GB to 55GB. The image looks as follows in terms of partitions:
boot partition volume group containing the following logical volumes: root.fs 4GB localhd.fs 62GB swap.fs 2GB
What I ended up doing was mounting this image and actually reducing the localhd logical volume by 15GB. Up until this point there were no issues.
My question is how do I actually reduce the image itself after reducing the size of the logical volume -- I'm assuming that the shrinkage by 15GB simply resulted in 15GB of free unallocated space. I want to get rid of that 15Gb all together.
