Re: [Openstack] Configuring instances during first boot
Hello, Thank you for your answers, Effectively I did'nt see this point ... I must now think about it ... I hope that copy ganlance image to cinder bootable volume will answer to this probleme. That's because in our hand made cloud, we use cobbler/kickstart to deploy every VM ... so no resize needed during the installation.

Cloud images are usually built as small as possible. For example the Ubuntu images are 2 GB in size. When an instance is launched, Nova resizes the image file according to the instance flavor selected (for example 10 GB for a small instance, 100 GB for an X large instance, aso). It is then up to the guest to make use of that additional disk space. One approach is to have a script the initramfs that enlarges the root partition to the max available size, ideally consuming the whole disk. Later in the boot process, cloud-init runs and online-resizes the root filesystem. Thus you end up with an instance with a root filesystem that consumes the whole disk. ...Juerg Thank you in advance.

Juerg, I'm interested/willing to help with this. I'd like for growpart to have support for GPT partitions also. Please let me know how I can help. One exciting thing is that newer kernels now support 'update' of a partition table, that should be a good fit for simplistic growing like we're interested in. util-linux has recently gained the ability to tell the kernel to update its partition table view at [1]. What that means is that going forward we won't have to do this stuff inside the initramfs, and I'd like for cloud-init to be able to drive it itself. -- [1] http://git.kernel.org/?p=utils/util-linux/util-linux.git;a=commitdiff;h=3b905b794e93609af7e42459d32b27e7c18ce02e ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
