The new CentOS 7 images run on an ext4 filesystem.
We’re using LVM as our back-end storage which supports online resizing LVs and then running resize2fs inside the running guest to resize a mounted volume (including /)
If we do this manually using lvresize on the host and resize2fs in the guest we can resize a running CentOS 7 guest. If we use Cloudmin it insists on shutting down the VM to perform the resize.
So my feature request is: please update Cloudmin to support online resizing of ext4 volumes!
Thanks
