Growpart
--------
**Summary:** grow partitions
Growpart resizes partitions to fill the available disk space.
This is useful for cloud instances with a larger amount of disk space available
than the pristine image uses, as it allows the instance to automatically make
use of the extra space.
The devices on which to run growpart are specified as a list under the
``devices`` key. Each entry in the devices list can be either the path to the
device's mountpoint in the filesystem or a path to the block device in
``/dev``.
The utility to use for resizing can be selected using the ``mode`` config key.
If the ``mode`` key is set to ``auto``, then any available utility (either
``growpart`` or BSD ``gpart``) will be used. If neither utility is available,
no error will be raised. If ``mode`` is set to ``growpart``, then the
``growpart`` utility will be used. If this utility is not available on the
system, this will result in an error. If ``mode`` is set to ``off`` or
``false``, then ``cc_growpart`` will take no action.
There is some functionality overlap between this module and the ``growroot``
functionality of ``cloud-initramfs-tools``. However, there are some situations
where one tool is able to function and the other is not. The default
configuration for both should work for most cloud instances. To explicitly
prevent ``cloud-initramfs-tools`` from running ``growroot``, the file
``/etc/growroot-disabled`` can be created. By default, both ``growroot`` and
``cc_growpart`` will check for the existence of this file and will not run if
it is present. However, this file can be ignored for ``cc_growpart`` by setting
``ignore_growroot_disabled`` to ``true``. For more information on
``cloud-initramfs-tools`` see: https://launchpad.net/cloud-initramfs-tools
Growpart is enabled by default on the root partition. The default config for
growpart is::
growpart:
mode: auto
devices: ["/"]
ignore_growroot_disabled: false
**Internal name:** ``cc_growpart``
**Module frequency:** always
**Supported distros:** all
**Config keys**::
growpart:
mode: <auto/growpart/off/false>
devices:
- "/"
- "/dev/vdb1"
ignore_growroot_disabled: <true/false>

GPT disks store metadata at the beginning (primary) and at the
end (secondary) of the disk. When launching an image with a
larger disk compared to the original image, the secondary copy
is lost. Thus, the metadata will be marked CORRUPT, and need to
be recovered.
