NAME <\/a> <\/h2>\n

btrfs-property \u2212 get\/set\/list properties for given filesystem object<\/p>\n

SYNOPSIS <\/a> <\/h2>\n

btrfs property<\/b> <\/i><\/p>\n

DESCRIPTION <\/a> <\/h2>\n

btrfs property<\/b><\/i> 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<\/b> subcommand for more information about both btrfs object and property.<\/p>\n

btrfs property<\/b> provides an unified and user\u2212friendly method to tune different btrfs properties instead of using the traditional method like chattr<\/b>(1) or lsattr<\/b>(1).<\/p>\n

SUBCOMMAND <\/a> <\/h2>\n

get<\/b> [\u2212t <\/i>] <\/i> [<\/i>]<\/p>\n

get property from a btrfs <\/i> of given <\/i><\/p>\n

A btrfs object, which is set by <\/i>, can be a btrfs filesystem itself, a btrfs subvolume, an inode (file or directory) inside btrfs, or a device on which a btrfs exists.<\/p>\n

The option \u2212t<\/i> 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.<\/p>\n

Possible types are s[ubvol]<\/i>, f[ilesystem]<\/i>, i[node]<\/i> and d[evice]<\/i>, where the first lettes is a shortcut.<\/p>\n

Set the name of property by name<\/i>. If no name<\/i> is specified, all properties for the given object are printed. name<\/i> is one of the following:<\/p>\n

ro<\/p>\n

read\u2212only flag of subvolume: true or false. Please also see section SUBVOLUME FLAGS<\/i> in btrfs\u2212subvolume<\/b>(8) for possible implications regarding incremental send.<\/p>\n

label<\/p>\n

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.<\/p>\n

compression<\/p>\n

compression algorithm set for an inode, possible values: lzo<\/i>, zlib<\/i>, zstd<\/i>. To disable compression use “” (empty string), no<\/i> or none<\/i>.<\/p>\n

list<\/b> [\u2212t <\/i>] <\/i><\/p>\n

Lists available properties with their descriptions for the given object.<\/p>\n

See the description of get<\/b> subcommand for the meaning of each option.<\/p>\n

set<\/b> [\u2212f] [\u2212t <\/i>] <\/i><\/p>\n

Sets a property on a btrfs object.<\/p>\n

See the description of get<\/b> subcommand for the meaning of each option.<\/p>\n

Options<\/b><\/p>\n

\u2212f<\/p>\n

Force the change. Changing some properties may involve safety checks or additional changes that depend on the properties semantics.<\/p>\n

EXIT STATUS <\/a> <\/h2>\n

btrfs property<\/b> returns a zero exit status if it succeeds. Non zero is returned in case of failure.<\/p>\n

AVAILABILITY <\/a> <\/h2>\n

btrfs<\/b> is part of btrfs\u2212progs. Please refer to the btrfs wiki http:\/\/btrfs.wiki.kernel.org<\/font><\/b> for further details.<\/font><\/p>\n
