Note that the service file warns us that it uses ``awk(1)``, and as such requires ``/usr`` to be present. However, cloud-init is installed into ``/usr/local``, so we should be fine. We invoke the ``growfs`` with ``service growfs onestart``, so it doesn't need to be enabled in ``rc.conf``. r7 c C s t j�d�o|dgkS )z'growfs only works on the root partitionz/etc/rc.d/growfsr )rE rF �isfiler- r# r# r$ r. � s zResizeGrowFS.availablec C sj t ||�}z| jjddd� W n< tjyZ } z"t�td� t|�|�W Y d }~n d }~0 0 |t ||�fS )NZonestart�growfs)�actionZservicez Failed: service growfs onestart) rD r) Zmanage_servicer r@ r rK rL r% )r* r/ r0 r1 r2 rM rN r# r# r$ r3 � s zResizeGrowFS.resizeN)r r! r" �__doc__r4 r. r3 r# r# r# r$ rP y s rP c @ s" e Zd Zed�dd�Zdd� ZdS )� ResizeGpartr7 c C sN z4t j ddgddiddgd�j}t�d|�r2W d S W n t jyH Y n0 d S ) N�gpart�helpr9 r: r rC )r< Zrcszgpart recover TF)r �stderrr> r? r@ )r* r �errr# r# r$ r. � s � zResizeGpart.availablec C s� zt � dd|g� W nH t jy\ } z.|jdkrHt�td|� t|�|�W Y d}~n d}~0 0 t||�}zt � ddd||g� W n@ t jy� } z&t�td||� t|�|�W Y d}~n d}~0 0 |t||�fS ) a9 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.
