Saltstack module disk 详解

disk.tune

Set attributes for the specified device

CLI Example:

salt '*' disk.tune /dev/sda1 read-ahead=1024 read-write=True

Valid options are: read-ahead, filesystem-read-ahead,
read-only, read-write.

See the blockdev(8) manpage for a more complete description of these
options.

disk.fstype

Return the filesystem name of the specified device

New in version 2016.11.0

device
The name of the device

CLI Example:

salt '*' disk.fstype /dev/sdX1

disk.wipe

Remove the filesystem information

CLI Example:

salt '*' disk.wipe /dev/sda1

disk.percent

Return partition information for volumes mounted on this minion

CLI Example:

salt '*' disk.percent /var

disk.smart_attributes

Fetch SMART attributes
Providing attributes will deliver only requested attributes
Providing values will deliver only requested values for attributes

Default is the Backblaze recommended
set (https://www.backblaze.com/blog/hard-drive-smart-stats/):
(5,187,188,197,198)

New in version 2016.3.0

CLI Example:

salt '' disk.smart_attributes /dev/sda
salt '' disk.smart_attributes /dev/sda attributes=(5,187,188,197,198)

disk.resize2fs

Resizes the filesystem.

CLI Example:
salt '*' disk.resize2fs /dev/sda1

disk.inodeusage

Return inode usage information for volumes mounted on this minion

CLI Example:

salt '*' disk.inodeusage

disk.format

Format a filesystem onto a device

New in version 2016.11.0

device
The device in which to create the new filesystem

fs_type
The type of filesystem to create

inode_size
Size of the inodes

This option is only enabled for ext and xfs filesystems

lazy_itable_init
If enabled and the uninit_bg feature is enabled, the inode table will
not be fully initialized by mke2fs. This speeds up filesystem
initialization noticeably, but it requires the kernel to finish
initializing the filesystem in the background when the filesystem
is first mounted. If the option value is omitted, it defaults to 1 to
enable lazy inode table zeroing.

This option is only enabled for ext filesystems

fat
FAT size option. Can be 12, 16 or 32, and can only be used on
fat or vfat filesystems.

force
Force mke2fs to create a filesystem, even if the specified device is
not a partition on a block special device. This option is only enabled
for ext and xfs filesystems

This option is dangerous, use it with caution.

CLI Example:

salt '*' disk.format /dev/sdX1

disk.dump

Return all contents of dumpe2fs for a specified device

CLI Example:
salt '*' disk.dump /dev/sda1

disk.blkid

Return block device attributes: UUID, LABEL, etc. This function only works
on systems where blkid is available.

device
Device name from the system

token
Any valid token used for the search

CLI Example:

salt '' disk.blkid
salt '' disk.blkid /dev/sda
salt '' disk.blkid token='UUID=6a38ee5-7235-44e7-8b22-816a403bad5d'
salt '' disk.blkid token='TYPE=ext4'

disk.usage

Return usage information for volumes mounted on this minion

Changed in version 2019.2.0

Default for SunOS changed to 1 kilobyte blocks

CLI Example:

salt '*' disk.usage
