Hi All,
Openstack is able to boot the same image with different disk sizes.
The instance's disk size is depends on the selected flavor type.
With the default flavor types you can have 20Gib(m1.small), 40Gib
(m1.medium), 80Gib (m1.large), 160 GiB (m1.xlarge) Disk sizes.
I am looking for an OpenStack friendly Fedora image which is able to
utilize all space on the first disk(vda), without any additional
manual steps. The file system should be ready for use before I login
to the instance.
According to this presentation
http://www.slideshare.net/openstack/os-summit-portlandimages, the
best time for resizing the file systems is at the initrd time.
All Fedora jeos images I tried so far just uses maximum 10 GiB even
on a 160 GiB disk after the first boot. I would like to use the same
image for all disk sizes.
Do you know about a working auto-resize capable Fedora Image ?
There is a package called cloud-utils-initramfs which does this in the
initramfs.
https://bugzilla.redhat.com/show_bug.cgi?id=916087
it should be trickling in and I hope will be into the imgs soon.
does this help?
