BTRFS-PROPERTY(8) Btrfs Manual BTRFS-PROPERTY(8)
btrfs-property - get/set/list properties for given filesystem object
btrfs property <subcommand> <args>
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).
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 device
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.
btrfs property returns a zero exit status if it succeeds. Non zero is
returned in case of failure.
