The call to fstrim in disk-image-create is currently useless, because at the time this is called, the file systems were already umounted by the block device layer. The current implementation of the block-device mount plugin does not call fstrim at all: resulting in larger image sizes. This patch removes the useless fstrim call from the disk-image-create script and moves this into the block-device mount.py. The resulting image might be much smaller. Example: Ubuntu Xenial with some elements; once with and once without this patch: -rw-r--r-- 1 dib dib 475661824 Sep 16 06:43 ubuntu-xenial-without-fstrim.qcow2 -rw-r--r-- 1 dib dib 364249088 Sep 16 09:30 ubuntu-xenial-with-fstrim.qcow2 Change-Id: I4e21ae50c5e6e26dc9f50f004ed6413132c81047 Signed-off-by: Andreas Florath <andreas@florath.net>
Image building tools for OpenStack
diskimage-builder is a flexible suite of components for
building a wide-range of disk images, filesystem images and ramdisk
images for use with OpenStack.
This repository has the core functionality for building such images, both virtual and bare metal. Images are composed using elements; while fundamental elements are provided here, individual projects have the flexibility to customise the image build with their own elements.
For example:
$ DIB_RELEASE=trusty disk-image-create -o ubuntu-trusty.qcow2 vm ubuntuwill create a bootable Ubuntu Trusty based qcow2
image.
diskimage-builder is useful to anyone looking to produce
customised images for deployment into clouds. These tools are the
components of TripleO that are
responsible for building disk images. They are also used extensively to
build images for testing OpenStack itself, particularly with nodepool.
Platforms supported include Ubuntu, CentOS, RHEL and Fedora.
