PartedL - command parted -l

This module provides processing for the parted command. The output is parsed by the PartedL class. Attributes are provided for each field for the disk, and a list of Partition class objects, one for each partition in the output.

Typical content of the parted -l command output looks like:

Model: ATA TOSHIBA MG04ACA4 (scsi)
Disk /dev/sda: 4001GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags: pmbr_boot

Number  Start   End     Size    File system  Name  Flags
 1      1049kB  2097kB  1049kB                     bios_grub
 2      2097kB  526MB   524MB   xfs
 3      526MB   4001GB  4000GB                     lvm

The columns may vary depending upon the type of device.

Note

The examples in this module may be executed with the following command:

python -m insights.parsers.parted

class insights.parsers.parted.PartedL(context, extra_bad_lines=[])[source]

Bases: insights.core.CommandParser

Class to represent attributes of the parted command output.

The columns may vary depending upon the type of device.

data

Dictionary of information returned by parted command.

Type

dict

partitions

The partitions found in the output, as Partition objects.

Type

list

boot_partition

the first partition marked as bootable, or None if one was not found.

Type

Partition

Raises

  • ParseException -- Raised if parted output indicates “error” or “warning” in first line, or if “disk” field is not present, or if there is an error parsing the data.

  • ValueError -- Raised if there is an error parsing the partition table.

property disk

Disk information.

Type

str

get(item)[source]

Returns a value for the specified item key.

property logical_sector_size

Logical part of sector size.

Type

str

parse_content(content)[source]

This method must be implemented by classes based on this class.

property physical_sector_size

Physical part of sector size.

class insights.parsers.parted.Partition(data)[source]

Bases: object

Class to contain information for one partition.

Represents the values from one row of the partition information from the parted command. Column names have been converted to lowercase and are provided as attributes. Column names may vary so the get method may be used to check for the presence of a column.
