salt.modules.extfs¶

Module for managing ext2/3/4 file systems

salt.modules.extfs.attributes(device, args=None)¶

Return attributes from dumpe2fs for a specified device

CLI Example:

salt '*' extfs.attributes /dev/sda1

salt.modules.extfs.blocks(device, args=None)¶

Return block and inode info from dumpe2fs for a specified device

CLI Example:

salt '*' extfs.blocks /dev/sda1

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

Return all contents of dumpe2fs for a specified device

CLI Example:

salt '*' extfs.dump /dev/sda1

salt.modules.extfs.mkfs(device, fs_type, **kwargs)¶

Create a file system on the specified device

CLI Example:

salt '*' extfs.mkfs /dev/sda1 fs_type=ext4 opts='acl,noexec'

Valid options are:

• block_size: 1024, 2048 or 4096

• check: check for bad blocks

• direct: use direct IO

• ext_opts: extended file system options (comma-separated)

• fragment_size: size of fragments

• force: setting force to True will cause mke2fs to specify the -F option twice (it is already set once); this is truly dangerous

• blocks_per_group: number of blocks in a block group

• number_of_groups: ext4 option for a virtual block group

• bytes_per_inode: set the bytes/inode ratio

• inode_size: size of the inode

• journal: set to True to create a journal (default on ext3/4)

• journal_opts: options for the fs journal (comma separated)

• blocks_file: read bad blocks from file

• label: label to apply to the file system

• reserved: percentage of blocks reserved for super-user

• last_dir: last mounted directory

• test: set to True to not actually create the file system (mke2fs -n)

• number_of_inodes: override default number of inodes

• creator_os: override "creator operating system" field

• opts: mount options (comma separated)

• revision: set the filesystem revision (default 1)

• super: write superblock and group descriptors only

• fs_type: set the filesystem type (REQUIRED)

• usage_type: how the filesystem is going to be used

• uuid: set the UUID for the file system

See the mke2fs(8) manpage for a more complete description of these options.

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

Set attributes for the specified device (using tune2fs)

CLI Example:

salt '*' extfs.tune /dev/sda1 force=True label=wildstallyns opts='acl,noexec'

Valid options are:

• max: max mount count

• count: mount count

• error: error behavior

• extended_opts: extended options (comma separated)

• force: force, even if there are errors (set to True)

• group: group name or gid that can use the reserved blocks

• interval: interval between checks

• journal: set to True to create a journal (default on ext3/4)

• journal_opts: options for the fs journal (comma separated)

• label: label to apply to the file system

• reserved: percentage of blocks reserved for super-user

• last_dir: last mounted directory

• opts: mount options (comma separated)

• feature: set or clear a feature (comma separated)

• mmp_check: mmp check interval

• reserved: reserved blocks count

• quota_opts: quota options (comma separated)

• time: time last checked

• user: user or uid who can use the reserved blocks

• uuid: set the UUID for the file system

See the mke2fs(8) manpage for a more complete description of these options.
