NAME

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

SYNOPSIS

       btrfs property <subcommand> <args>

DESCRIPTION

       btrfs property is used to get/set/list property for given btrfs object. 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>]
           Gets a property from a btrfs object.

           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 -t <type> option 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].

           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 followings.

           ro
               read-only flag of subvolume: true or false

           label
               label of device

           compression
               compression setting for an inode: lzo, zlib, or "" (empty string)

       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.
