Title:
  On the latest centos 7 release, we are unable to resize our instances
  filesystems

Status in cloud-init:
  Expired
Status in cloud-init package in CentOS:
  Unknown

Bug description:
  Since the CentOS 7 update to cloud-init 0.7.9, we've been unable to
  resize our instance's root drives. Of course, since root volume resize
  is not officially supported in openstack, what we do is a bit of hack.
  We basically shutdown the vm -> cinder reset-state --state available
  *volume id* -> cinder extend *volume id* *size* -> cinder reset-state
  --state in-use *volume-id* -> migrate the VM (to remake the iscsi
  mount) -> startup the VM. This increases the volume size and still
  works. The issue is when cloud-init needs to execute the growpart
  module.

  See https://bugs.centos.org/view.php?id=13931

  The only error we get is related to vendordata, which may be preventing the resize process to happen :

  2017-09-28 02:01:43,641 - util.py[DEBUG]: failed stage init

      return text.encode(encoding)
  AttributeError: 'dict' object has no attribute 'encode'

  This is on openstack Ocata though, and the vendordata has always been
  empty, as we use the default settings for it.

  Cloud provider: we are the cloud provider, PlanetHoster, using Openstack Ocata.
  version: Cloud-init 0.7.9-9.el7.centos.2

  relevant cloud-init config:

  cloud_init_modules:
   - migrator
   - bootcmd
   - write-files
   - growpart
   - resizefs
   - update_etc_hosts
   - rsyslog
   - users-groups
