salt.modules.blockdev¶

Module for managing block devices

salt.modules.blockdev.dump(device, args=None)¶

Return all contents of dumpe2fs for a specified device

args

a list containing only the desired arguments to return

CLI Example:

salt '*' blockdev.dump /dev/sdX1

salt.modules.blockdev.format(device, fs_type='ext4', inode_size=None, lazy_itable_init=None)¶

Format a filesystem onto a block device

New in version 2015.8.2.

device

The block 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

CLI Example:

salt '*' blockdev.format /dev/sdX1

salt.modules.blockdev.fstype(device)¶

Return the filesystem name of a block device

New in version 2015.8.2.

device

The name of the block device

CLI Example:

salt '*' blockdev.fstype /dev/sdX1

salt.modules.blockdev.resize2fs(device)¶

Resizes the filesystem.

CLI Example: .. code-block:: bash

salt '*' blockdev.resize2fs /dev/sdX1

salt.modules.blockdev.tune(device, **kwargs)¶

Set attributes for the specified device

CLI Example:

salt '*' blockdev.tune /dev/sdX1 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.

salt.modules.blockdev.wipe(device)¶

Remove the filesystem information

CLI Example:

salt '*' blockdev.wipe /dev/sdX1
