Supported Linux distributions: CentOS 6, Debian 6, Debian 7.
Rework of my previous project, that was limited only to CentOS 6.
This tool creates new initrd (initramfs) image with ability to resize root filesystem over available space. Tipically you need this when you provision your virtual machine on OpenStack cloud for the first time (your image becomes flavor aware)
For now, filesystem resize is limited to ext2, ext3 and ext4 (resize2fs) including LVM volumes.
This code was successfuly tested on: CentOS 6.5, Debian 6 and Debian 7.2
cloud-utils (https://launchpad.net/cloud-utils) parted (CentOS)
Install git, clone this project on your machine, run 'install'.
cd /opt rpm -ivh http://ftp-stud.hs-esslingen.de/pub/epel/6/i386/epel-release-6-8.noarch.rpm yum install git parted cloud-utils git clone https://github.com/flegmatik/linux-rootfs-resize.git cd linux-rootfs-resize ./install
Tool is designed in modular fashion, so support for other distributions can be added without much work (I hope).
