[BTRFS-PROPERTY(8)](https://www.chedong.com/phpMan.php/man/BTRFS-PROPERTY/8/markdown)                           Btrfs Manual                           [BTRFS-PROPERTY(8)](https://www.chedong.com/phpMan.php/man/BTRFS-PROPERTY/8/markdown)



## NAME
       btrfs-property - get/set/list properties for given filesystem object

## SYNOPSIS
       **btrfs** **property** _<subcommand>_ _<args>_

## DESCRIPTION
       **btrfs** **property** is used to get/set/list property for given filesystem object. The object can
       be an inode (file or directory), subvolume or the whole filesystem. See the description of
       **get** subcommand for more information about both btrfs object and property.

       **btrfs** **property** provides an unified and user-friendly method to tune different btrfs
       properties instead of using the traditional method like [**chattr**(1)](https://www.chedong.com/phpMan.php/man/chattr/1/markdown) or [**lsattr**(1)](https://www.chedong.com/phpMan.php/man/lsattr/1/markdown).

## SUBCOMMAND
       **get** [-t _<type>_] _<object>_ [_<name>_]
           get property from a btrfs _<object>_ of given _<type>_

           A btrfs object, which is set by _<object>_, can be a btrfs filesystem itself, a btrfs
           subvolume, an inode (file or directory) inside btrfs, or a device on which a btrfs
           exists.

           The option _-t_ can be used to explicitly specify what type of object you meant. This is
           only needed when a property could be set for more then one object type.

           Possible types are _s[ubvol]_, _f[ilesystem]_, _i[node]_ and _d[evice]_, where the first lettes
           is a shortcut.

           Set the name of property by _name_. If no _name_ is specified, all properties for the given
           object are printed.  _name_ is one of the following:

           ro
               read-only flag of subvolume: true or false. Please also see section _SUBVOLUME_ _FLAGS_
               in [**btrfs-subvolume**(8)](https://www.chedong.com/phpMan.php/man/btrfs-subvolume/8/markdown) for possible implications regarding incremental send.

           label
               label of the filesystem. For an unmounted filesystem, provide a path to a block
               device as object. For a mounted filesystem, specify a mount point.

           compression
               compression algorithm set for an inode, possible values: _lzo_, _zlib_, _zstd_. To disable
               compression use "" (empty string), _no_ or _none_.

       **list** [-t _<type>_] _<object>_
           Lists available properties with their descriptions for the given object.

           See the description of **get** subcommand for the meaning of each option.

       **set** [-f] [-t _<type>_] _<object>_ _<name>_ _<value>_
           Sets a property on a btrfs object.

           See the description of **get** subcommand for the meaning of each option.

           **Options**

           -f
               Force the change. Changing some properties may involve safety checks or additional
               changes that depend on the properties semantics.

## EXIT STATUS
       **btrfs** **property** returns a zero exit status if it succeeds. Non zero is returned in case of
       failure.

## AVAILABILITY
       **btrfs** is part of btrfs-progs. Please refer to the btrfs wiki **<http://btrfs.wiki.kernel.org>** for
       further details.
