NAME         top

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

SYNOPSIS         top

       btrfs property <subcommand> <args>

DESCRIPTION         top

       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         top

       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

               read-only flag of subvolume: true or false

               label of device

               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

           See the description of get subcommand for the meaning of each

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

           See the description of get subcommand for the meaning of each
