This module is useful along with ``cc_growpart`` and will ensure that if the root partition has been resized the root filesystem will be resized along with it. By default, ``cc_resizefs`` will resize the root partition and will block the boot process while the resize command is running. Optionally, the resize operation can be performed in the background while cloud-init continues running modules. This can be enabled by setting ``resize_rootfs`` to ``noblock``. This module can be disabled altogether by setting ``resize_rootfs`` to ``false``.z@resize_rootfs: false # disable root filesystem resize operationzAresize_rootfs: noblock # runs resize operation in the background)�id�name�title� descriptionZdistrosZexamplesZ frequencyZactivate_by_schema_keysc C s� t j| � r0tjjd| �r0ddddd| g}ndddd| g}t jjd�}t jjtjddg�d jd �d j � �}||kr�|j d�}|j |d d � t |�S ) Nz %s/.snapshots�btrfsZ filesystem�resize�maxz5.10z --versionr �v� z --enqueue���) r Zmount_is_read_write�os�path�isdirZVersionZfrom_strr �split�strip�index�insert�tuple)� mount_point�devpth�cmdZbtrfs_with_queueZsystem_btrfs_ver�idx� r! �!/usr/lib/python3.6/cc_resizefs.py� _resize_btrfs8 s " r# c C s d|fS )NZ resize2fsr! )r r r! r! r" � _resize_extY s r$ c C s d| fS )NZ xfs_growfsr! )r r r! r! r" � _resize_xfs] s r% c C s dd| fS )N�growfsz-yr! )r r r! r! r" � _resize_ufsa s r' c C s ddd| |fS )N�zpoolZonlinez-er! )r r r! r! r" � _resize_zfse s r) c C s dd| fS )N�hammer2r& r! )r r r! r! r" �_resize_hammer2i s r+ c C s ddd|fS )zSingle device resize�bcachefsZdevicer r! )r r r! r! r" �_resize_bcachefsm s r- c C sd d}d}yt j dd|g� W nB t jk r^ } z$|jj|�rJ||jkrJdS |�W Y d d }~X nX dS )Nzgrowfs: requested sizez.is not larger than the current filesystem sizer& z-NTF)r �ProcessExecutionError�stderr� startswith)r r Z skip_startZ skip_contain�er! r! r" �_can_skip_resize_ufsr s r2 r ZextZxfsZufs�zfsr* r, c C s6 | j � }x(tj� D ] \}}|j|�r|||�S qW dS )NF)�lower�RESIZE_FS_PRECHECK_CMDS�itemsr0 )�fs_type� resize_whatr � fstype_lc�i�funcr! r! r" �can_skip_resize� s r< c C s� t j� }| dkrTtjj| � rT| rTt jt j� �} | dkrHtjd� dS tj d| � | dkrntj d| |� dS | j d�r�tj d� | S | j d � r�tjj| � r�d | j d � }tj d | |� |} ytj | �}W nf t k �r4 } zH|o�|jtjk�rtj d | |� n"|jtjk�r"tjd | |� n|�dS d}~X nX t j|j� �r~t j|j� �r~|�rltj d| |� ntjd| |� dS | S )a� Return updated devpath if the devpath is a writable block device. @param devpath: Requested path to the root device we want to resize. @param info: String representing information about the requested device. @param log: Logger to which logs will be added upon error. @returns devpath or updated devpath per kernel commandline if the device path is a writable block device, returns None otherwise. z /dev/rootNz!Unable to find device '/dev/root'z.Converted /dev/root to '%s' per kernel cmdlineZ overlayrootz)Not attempting to resize devpath '%s': %szgpt/z#We have a gpt label - just go aheadz/dev/�/z:'%s' doesn't appear to be a valid device path.
