Description

This interface is used for org.freedesktop.UDisks2.Block devices that contain a partition table.

Method Details

The CreatePartition() method

CreatePartition (IN  t     offset,
                 IN  t     size,
                 IN  s     type,
                 IN  s     name,
                 IN  a{sv} options,
                 OUT o     created_partition);

Creates a new partition.

Note that the created partition won't necessarily be created at the exact offset but slightly behind due to disk geometry and other alignment constraints (e.g. 1MiB alignment).

The newly created partition may also end up being slightly larger than the requested size bytes for the same reasons. The maximal size can be automatically set by using 0 as size.

For dos partition tables, the partition type can be set with the partition-type option. Possible values are: "primary", "extended" or "logical".

The newly created partition will be wiped of known filesystem signatures using the wipefs(8) command.

IN t offset:

The desired offset where the partition should be created, in bytes.

IN t size:

The desired size of the partition, in bytes (0 for maximal size).

IN s type:

The type of partition to create (cf. the "Type" property) or blank to use the default for the partition table type and OS.

IN s name:

The name for the new partition or blank if the partition table do not support names.

IN a{sv} options:

Options - known options (in addition to standard options) include partition-type (of type 's').

OUT o created_partition:

An object path to the created block device object implementing the org.freedesktop.UDisks2.Partition interface.


The CreatePartitionAndFormat() method

CreatePartitionAndFormat (IN  t     offset,
                          IN  t     size,
                          IN  s     type,
                          IN  s     name,
                          IN  a{sv} options,
                          IN  s     format_type,
                          IN  a{sv} format_options,
                          OUT o     created_partition);

This is a combination of org.freedesktop.UDisks2.PartitionTable:CreatePartition and org.freedesktop.UDisks2.Block:Format. After creating the partition, the resulting block device is formatted.

IN t offset:

The desired offset where the partition should be created, in bytes.

IN t size:

The desired size of the partition, in bytes (0 for maximal size).

IN s type:

The type of partition to create (cf. the "Type" property) or blank to use the default for the partition table type and OS.

IN s name:

The name for the new partition or blank if the partition table do not support names.

IN a{sv} options:

Options - known options (in addition to standard options) include partition-type (of type 's').

IN s format_type:

The type to use for Format.

IN a{sv} format_options:

Options for Format.

OUT o created_partition:

An object path to the created block device object implementing the org.freedesktop.UDisks2.Partition interface.
