Parted Parsers

Classes to parse parted command information.

Parsers provided by this module include:

PartedL - command parted -l -s

class insights.parsers.parted.PartedDevice(content)

Bases: object

Class to contain information for one device of parted command output.

The columns of partation table may vary depending upon the type of device.

device_info

Dictionary of information of this device.

Type:

dict

partitions

The partitions of this device, 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 command output of this device indicates “error” or “warning” in first line, or if “disk” field is not present, or if there is an error parsing the data.

property data

Device information.

Type:

dict

property disk

Disk information.

Type:

str

get(item)

Returns a value for the specified item key.

property logical_sector_size

Logical part of sector size.

Type:

str

property physical_sector_size

Physical part of sector size.

Type:

str

class insights.parsers.parted.PartedL(context, extra_bad_lines=None)

Bases: CommandParser

Class to represent attributes of the parted -l -s command output.

devices_info

The devices found in the output, as PartedDevice objects.

Type:

list

Typical content of the parted -l -s 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


Model: IBM 2107900 (scsi)
Disk /dev/sdb: 2147MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number  Start   End     Size    Type     File system  Flags
 1      32.3kB  2580kB  2548kB  primary

The columns of partation table 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

Examples

>>> [device.disk for device in parted_l_results]
['/dev/sda', '/dev/sdb']
>>> parted_info = parted_l_results.get('/dev/sda')
>>> sorted(parted_info.device_info.items())
[('disk', '/dev/sda'), ('disk_flags', 'pmbr_boot'), ('model', 'ATA TOSHIBA MG04ACA4 (scsi)'), ('partition_table', 'gpt'), ('sector_size', '512B/512B'), ('size', '4001GB')]
>>> parted_info.device_info['model']
'ATA TOSHIBA MG04ACA4 (scsi)'
>>> parted_info.disk
'/dev/sda'
>>> parted_info.logical_sector_size
'512B'
>>> parted_info.physical_sector_size
'512B'
>>> parted_info.boot_partition
>>> parted_info.device_info['disk_flags']
'pmbr_boot'
>>> len(parted_info.partitions)
3
>>> sorted(parted_info.partitions[0].data.items())
[('end', '2097kB'), ('file_system', ''), ('flags', 'bios_grub'), ('name', ''), ('number', '1'), ('size', '1049kB'), ('start', '1049kB')]
>>> parted_info.partitions[0].number
'1'
>>> parted_info.partitions[0].start
'1049kB'
>>> parted_info.partitions[0].end
'2097kB'
>>> parted_info.partitions[0].size
'1049kB'
>>> parted_info.partitions[0].file_system
''
>>> parted_info.partitions[0].type
>>> parted_info.partitions[0].flags
'bios_grub'

get(disk_name)

Returns a value for the specified item key.

parse_content(content)

Divide “content” into each device section by two empty lines.

class insights.parsers.parted.Partition(data)

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.

data

Dictionary of partition information keyed by column names in lowercase.

Type:

dict

property end

Ending location for the partition.

Type:

str

property file_system

File system type.

Type:

str

property flags

Partition flags.

Type:

str

get(item)

Get information for column item or None if not present.

property number

Partition number.

Type:

str

property size

Size of the partition.

Type:

str

property start

Starting location for the partition.

Type:

str

property type

File system type.

Type:

str
