btrfs property subcommand [options] path [property [value]]

btrfs property manages properties on btrfs filesystem objects including files, directories, subvolumes, filesystems, and devices. Properties control behavior like compression, read-only status, and labels.
Different object types support different properties. The list command shows what properties are available for each object.

-t type

Object type: subvol, filesystem, inode, or device

list

List available properties and descriptions

Get property values

Set a property value

compression

Compression algorithm for files: zstd, zlib, lzo, none

Filesystem label (filesystem property)

Read-only status (subvolume property)

Setting compression on a directory only affects new files; existing files need explicit recompression. Not all properties are writable. Some operations require root privileges.
