# Cloud-init supports the creation of simple partition tables and file systems # on devices. # Default disk definitions for AWS # -------------------------------- # (Not implemented yet, but provided for future documentation) disk_setup: ephmeral0: table_type: 'mbr' layout: True overwrite: False fs_setup: - label: None, filesystem: ext3 device: ephemeral0 partition: auto # Default disk definitions for Microsoft Azure # ------------------------------------------ device_aliases: {'ephemeral0': '/dev/sdb'} disk_setup: ephemeral0: table_type: mbr layout: True overwrite: False fs_setup: - label: ephemeral0 filesystem: ext4 device: ephemeral0.1 replace_fs: ntfs # Data disks definitions for Microsoft Azure # ------------------------------------------ disk_setup: /dev/disk/azure/scsi1/lun0: table_type: gpt layout: True overwrite: True fs_setup: - device: /dev/disk/azure/scsi1/lun0 partition: 1 filesystem: ext4 # Default disk definitions for SmartOS # ------------------------------------ device_aliases: {'ephemeral0': '/dev/vdb'} disk_setup: ephemeral0: table_type: mbr layout: False overwrite: False fs_setup: - label: ephemeral0 filesystem: ext4 device: ephemeral0.0 # Cavaut for SmartOS: if ephemeral disk is not defined, then the disk will # not be automatically added to the mounts. # The default definition is used to make sure that the ephemeral storage is # setup properly. # "disk_setup": disk partitioning # -------------------------------- # The disk_setup directive instructs Cloud-init to partition a disk. The format is: disk_setup: ephmeral0: table_type: 'mbr' layout: 'auto' /dev/xvdh: table_type: 'mbr' layout: - 33 - [33, 82] - 33 overwrite: True # The format is a list of dicts of dicts. The first value is the name of the # device and the subsequent values define how to create and layout the # partition. # The general format is: # disk_setup: # <DEVICE>: # table_type: 'mbr' # layout: <LAYOUT|BOOL> # overwrite: <BOOL> # # Where: # <DEVICE>: The name of the device. 'ephemeralX' and 'swap' are special # values which are specific to the cloud. For these devices # Cloud-init will look up what the real devices is and then # use it. # # For other devices, the kernel device name is used. At this # time only simply kernel devices are supported, meaning # that device mapper and other targets may not work. # # Note: At this time, there is no handling or setup of # device mapper targets. # # table_type=<TYPE>: Currently the following are supported: # 'mbr': default and setups a MS-DOS partition table # 'gpt': setups a GPT partition table # # Note: At this time only 'mbr' and 'gpt' partition tables # are allowed. It is anticipated in the future that # we'll also have "RAID" to create a mdadm RAID. # # layout={...}: The device layout. This is a list of values, with the # percentage of disk that partition will take. # Valid options are: # [<SIZE>, [<SIZE>, <PART_TYPE]] # # Where <SIZE> is the _percentage_ of the disk to use, while # <PART_TYPE> is the numerical value of the partition type. # # The following setups two partitions, with the first # partition having a swap label, taking 1/3 of the disk space # and the remainder being used as the second partition. # /dev/xvdh': # table_type: 'mbr' # layout: # - [33,82] # - 66 # overwrite: True # # When layout is "true" it means single partition the entire # device. # # When layout is "false" it means don't partition or ignore # existing partitioning. # # If layout is set to "true" and overwrite is set to "false", # it will skip partitioning the device without a failure. # # overwrite=<BOOL>: This describes whether to ride with saftey's on and # everything holstered. # # 'false' is the default, which means that: # 1. The device will be checked for a partition table # 2. The device will be checked for a file system # 3. If either a partition of file system is found, then # the operation will be _skipped_. # # 'true' is cowboy mode. There are no checks and things are # done blindly. USE with caution, you can do things you # really, really don't want to do. # # # fs_setup: Setup the file system # ------------------------------- # # fs_setup describes the how the file systems are supposed to look. fs_setup: - label: ephemeral0 filesystem: 'ext3' device: 'ephemeral0' partition: 'auto' - label: mylabl2 filesystem: 'ext4' device: '/dev/xvda1' - cmd: mkfs -t %(filesystem)s -L %(label)s %(device)s label: mylabl3 filesystem: 'btrfs' device: '/dev/xvdh' # The general format is: # fs_setup: # - label: <LABEL> # filesystem: <FS_TYPE> # device: <DEVICE> # partition: <PART_VALUE> # overwrite: <OVERWRITE> # replace_fs: <FS_TYPE> # # Where: # <LABEL>: The file system label to be used. If set to None, no label is # used. # # <FS_TYPE>: The file system type. It is assumed that the there # will be a "mkfs.<FS_TYPE>" that behaves likes "mkfs". On a standard # Ubuntu Cloud Image, this means that you have the option of ext{2,3,4}, # and vfat by default. # # <DEVICE>: The device name. Special names of 'ephemeralX' or 'swap' # are allowed and the actual device is acquired from the cloud datasource. # When using 'ephemeralX' (i.e. ephemeral0), make sure to leave the # label as 'ephemeralX' otherwise there may be issues with the mounting # of the ephemeral storage layer. # # If you define the device as 'ephemeralX.Y' then Y will be interpetted # as a partition value. However, ephermalX.0 is the _same_ as ephemeralX. # # <PART_VALUE>: # Partition definitions are overwriten if you use the '<DEVICE>.Y' notation. # # The valid options are: # "auto|any": tell cloud-init not to care whether there is a partition # or not. Auto will use the first partition that does not contain a # file system already. In the absence of a partition table, it will # put it directly on the disk. # # "auto": If a file system that matches the specification in terms of # label, type and device, then cloud-init will skip the creation of # the file system. # # "any": If a file system that matches the file system type and device, # then cloud-init will skip the creation of the file system. # # Devices are selected based on first-detected, starting with partitions # and then the raw disk. Consider the following: # NAME FSTYPE LABEL # xvdb # |-xvdb1 ext4 # |-xvdb2 # |-xvdb3 btrfs test # \-xvdb4 ext4 test # # If you ask for 'auto', label of 'test, and file system of 'ext4' # then cloud-init will select the 2nd partition, even though there # is a partition match at the 4th partition. # # If you ask for 'any' and a label of 'test', then cloud-init will # select the 1st partition. # # If you ask for 'auto' and don't define label, then cloud-init will # select the 1st partition. # # In general, if you have a specific partition configuration in mind, # you should define either the device or the partition number. 'auto' # and 'any' are specifically intended for formating ephemeral storage or # for simple schemes. # # "none": Put the file system directly on the device. # # <NUM>: where NUM is the actual partition number. # # <OVERWRITE>: Defines whether or not to overwrite any existing # filesystem. # # "true": Indiscriminately destroy any pre-existing file system. Use at # your own peril. # # "false": If an existing file system exists, skip the creation. # # <REPLACE_FS>: This is a special directive, used for Microsoft Azure that # instructs cloud-init to replace a file system of <FS_TYPE>. NOTE: # unless you define a label, this requires the use of the 'any' partition # directive. # # Behavior Caveat: The default behavior is to _check_ if the file system exists. # If a file system matches the specification, then the operation is a no-op.
