Chapter 14. Viewing the partition table with parted

Display the partition table of a block device to see the partition layout and details about individual partitions. You can view the partition table on a block device using the parted utility.

Procedure

  1. Start the parted utility. For example, the following output lists the device /dev/sda: 

    # parted /dev/sda

  2. View the partition table: 

    # (parted) print

Model: ATA SAMSUNG MZNLN256 (scsi)
Disk /dev/sda: 256GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

Number  Start   End     Size    Type      File system  Flags
 1      1049kB  269MB   268MB   primary   xfs          boot
 2      269MB   34.6GB  34.4GB  primary
 3      34.6GB  45.4GB  10.7GB  primary
 4      45.4GB  256GB   211GB   extended
 5      45.4GB  256GB   211GB   logical

  3. Optional: Switch to the device you want to examine next: 

    # (parted) select block-device

For a detailed description of the print command output, see the following:

Model: ATA SAMSUNG MZNLN256 (scsi)
The disk type, manufacturer, model number, and interface.
Disk /dev/sda: 256GB
The file path to the block device and the storage capacity.
Partition Table: msdos
The disk label type.
Number
The partition number. For example, the partition with minor number 1 corresponds to /dev/sda1.
Start and End
The location on the device where the partition starts and ends.
Type
Valid types are metadata, free, primary, extended, or logical.
File system
The file system type. If the File system field of a device shows no value, this means that its file system type is unknown. The parted utility cannot recognize the file system on encrypted devices.
