7

SYNOPSIS

9       btrfs property <subcommand> <args>
10

DESCRIPTION

12       btrfs property is used to get/set/list property for given btrfs object.
13       See the description of get subcommand for more information about both
14       btrfs object and property.
15
16       btrfs property provides an unified and user-friendly method to tune
17       different btrfs properties instead of using the traditional method like
18       chattr(1) or lsattr(1).
19

SUBCOMMAND

21       get [-t <type>] <object> [<name>]
22           Gets a property from a btrfs object.
23
24           A btrfs object, which is set by <object>, can be a btrfs filesystem
25           itself, a btrfs subvolume, an inode(file or directory) inside
26           btrfs, or a device on which a btrfs exists.
27
28           The -t <type> option can be used to explicitly specify what type of
29           object you meant. This is only needed when a property could be set
30           for more then one object type.
31
32           Possible types are s[ubvol], f[ilesystem], i[node] and d[evice].
33
34           Set the name of property by <name>. If no <name> is specified, all
35           properties for the given object are printed.  <name> is one of the
36           followings.
