Hi,
Been trying like mad to find a way to resize the partition of a EL7 VM template from the initramfs (basically run fdisk on /dev/vda) as I did for EL6, but with the new systemd+dracut it seems like either I find the disks in a nonexistent state or they are already in use. I think I went through all relevant hooks; pre-mount is a lie, at that stage the disk is seemingly already in use. :)
Does anyone have a tip how to go about this?

You don’t need to do it in initramfs any more.
cloud-init runs ‘growpart’ during the normal startup routine and it works fine on the newer kernels that can handle a running partition size change.
So just install ‘cloud-utils-growpart’ and either let cloud-init take care of it or run ‘growpart’ yourself.

Ah, meh. I was using the 0.7.4 cloud-init from EL6 (rebuilt) which doesn't do the growpart bit. I'll update my configs.
Thanks, Neil.
