'btrfs property' is used to get/set/list property, like lable or compression

'btrfs property' provides an unified and user-friendly method to tune different

SUBCOMMAND
----------
'get' [-t <type>] <object> [<name>]::
Gets a property from a btrfs object.
+
If no name is specified, all properties for the given object are
printed.
A filesystem object can be a the filesystem itself, a subvolume,
an inode or a device.
+
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]'.
+
The <object> can be path of btrfs device, btrfs mount point, or any
directories/files inside btrfs.

'set' [-t <type>] <object> <name> <value>::
Sets a property on a btrfs object.
+
See description of 'get' subcommand for a description of objects and object
types.

Lists available properties with their descriptions for the given object.
+
Please see the help of 'btrfs property get' for a description of
