BTRFS-PROPERTY(8)                Btrfs Manual                BTRFS-PROPERTY(8)

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) or lsattr(1).

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

           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 [-t _type_] _object_ _name_ _value_
           Sets a property on a btrfs object.

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

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