salt.modules.parted

Module for managing partitions on POSIX-like systems.

depends:
  • parted, partprobe, lsblk (usually parted and util-linux packages)

Some functions may not be available, depending on your version of parted.

Check the manpage for parted(8) for more information, or the online docs at:

http://www.gnu.org/software/parted/manual/html_chapter/parted_2.html

In light of parted not directly supporting partition IDs, some of this module has been written to utilize sfdisk instead. For further information, please reference the man page for sfdisk(8).

salt.modules.parted.align_check(device, part_type, partition)

Check if partition satisfies the alignment constraint of part_type. Type must be "minimal" or "optimal".

CLI Example:

salt '*' partition.align_check /dev/sda minimal 1
salt.modules.parted.check(device, minor)

Checks if the file system on partition <minor> has any errors.

CLI Example:

salt '*' partition.check 1
salt.modules.parted.cp(device, from_minor, to_minor)

Copies the file system on the partition <from-minor> to partition <to-minor>, deleting the original contents of the destination partition.

CLI Example:

salt '*' partition.cp /dev/sda 2 3
salt.modules.parted.exists(device=u'')

Check to see if the partition exists

CLI Example:

salt '*' partition.exists /dev/sdb1
salt.modules.parted.get_block_device()

Retrieve a list of disk devices

New in version 2014.7.0.

CLI Example:

salt '*' partition.get_block_device
salt.modules.parted.get_id(device, minor)

Prints the system ID for the partition. Some typical values are:

 b: FAT32 (vfat)
 7: HPFS/NTFS
82: Linux Swap
83: Linux
8e: Linux LVM
fd: Linux RAID Auto

CLI Example:

salt '*' partition.get_id /dev/sda 1
salt.modules.parted.list(device, unit=None)

Prints partition information of given <device>

CLI Examples:

salt '*' partition.list /dev/sda
salt '*' partition.list /dev/sda unit=s
salt '*' partition.list /dev/sda unit=kB
salt.modules.parted.mkfs(device, fs_type)

Makes a file system <fs_type> on partition <device>, destroying all data that resides on that partition. <fs_type> must be one of "ext2", "fat32", "fat16", "linux-swap" or "reiserfs" (if libreiserfs is installed)

CLI Example:

salt '*' partition.mkfs /dev/sda2 fat32
salt.modules.parted.mklabel(device, label_type)

Create a new disklabel (partition table) of label_type.

Type should be one of "aix", "amiga", "bsd", "dvh", "gpt", "loop", "mac", "msdos", "pc98", or "sun".

CLI Example:

salt '*' partition.mklabel /dev/sda msdos
salt.modules.parted.mkpart(device, part_type, fs_type=None, start=None, end=None)

Make a part_type partition for filesystem fs_type, beginning at start and ending at end (by default in megabytes). part_type should be one of "primary", "logical", or "extended".

CLI Examples:

salt '*' partition.mkpart /dev/sda primary fs_type=fat32 start=0 end=639
salt '*' partition.mkpart /dev/sda primary start=0 end=639
salt.modules.parted.mkpartfs(device, part_type, fs_type, start, end)

Make a <part_type> partition with a new filesystem of <fs_type>, beginning at <start> and ending at <end> (by default in megabytes).

<part_type> should be one of "primary", "logical", or "extended". <fs_type> must be one of "ext2", "fat32", "fat16", "linux-swap" or "reiserfs" (if libreiserfs is installed)

CLI Example:

salt '*' partition.mkpartfs /dev/sda logical ext2 440 670
salt.modules.parted.name(device, partition, name)

Set the name of partition to name. This option works only on Mac, PC98, and GPT disklabels. The name can be placed in quotes, if necessary.

CLI Example:

salt '*' partition.name /dev/sda 1 'My Documents'
salt.modules.parted.probe(*devices)

Ask the kernel to update its local partition data. When no args are specified all block devices are tried.

Caution: Generally only works on devices with no mounted partitions and may take a long time to return if specified devices are in use.

CLI Examples:

salt '*' partition.probe
salt '*' partition.probe /dev/sda
salt '*' partition.probe /dev/sda /dev/sdb
salt.modules.parted.rescue(device, start, end)

Rescue a lost partition that was located somewhere between start and end. If a partition is found, parted will ask if you want to create an entry for it in the partition table.

CLI Example:

salt '*' partition.rescue /dev/sda 0 8056
salt.modules.parted.resize(device, minor, start, end)

Resizes the partition with number <minor>.

The partition will start <start> from the beginning of the disk, and end <end> from the beginning of the disk. resize never changes the minor number. Extended partitions can be resized, so long as the new extended partition completely contains all logical partitions.

CLI Example:

salt '*' partition.resize /dev/sda 3 200 850
salt.modules.parted.rm(device, minor)

Removes the partition with number <minor>.

CLI Example:

salt '*' partition.rm /dev/sda 5
salt.modules.parted.set(device, minor, flag, state)

Changes a flag on the partition with number <minor>.

A flag can be either "on" or "off" (make sure to use proper quoting, see YAML Idiosyncrasies). Some or all of these flags will be available, depending on what disk label you are using.

Valid flags are: bios_grub, legacy_boot, boot, lba, root, swap, hidden, raid,
LVM, PALO, PREP, DIAG

CLI Example:

salt '*' partition.set /dev/sda 1 boot '"on"'
salt.modules.parted.set_id(device, minor, system_id)

Sets the system ID for the partition. Some typical values are:

 b: FAT32 (vfat)
 7: HPFS/NTFS
82: Linux Swap
83: Linux
8e: Linux LVM
fd: Linux RAID Auto

CLI Example:

salt '*' partition.set_id /dev/sda 1 83
salt.modules.parted.system_types()

List the system types that are supported by the installed version of sfdisk

CLI Example:

salt '*' partition.system_types
salt.modules.parted.toggle(device, partition, flag)
Toggle the state of <flag> on <partition>. Valid flags are the same as
the set command.

CLI Example:

salt '*' partition.toggle /dev/sda 1 boot
