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.
