btrfs-property(8) ================= NAME ---- btrfs-property - get/set/list properties for given filesystem object SYNOPSIS -------- *btrfs property* DESCRIPTION ----------- *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). SUBCOMMAND ---------- *get* [-t ] []:: get property from a btrfs of given + A btrfs object, which is set by , 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 the filesystem. For an unmounted filesystem, provide a path to a block device as object. For a mounted filesystem, specify a mount point. compression:::: compression algorithm set for an inode, possible values: 'lzo', 'zlib', 'zstd'. To disable compression use "" (empty string), 'no' or 'none'. *list* [-t ] :: Lists available properties with their descriptions for the given object. + See the description of *get* subcommand for the meaning of each option. *set* [-t ] :: 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. AVAILABILITY ------------ *btrfs* is part of btrfs-progs.
