The max value one can set is 64k. + +*rootid* <path>:: +For a given file or directory, return the containing tree root id. For a +subvolume return it's own tree id. ++ +The result is undefined for the so-called empty subvolumes (identified by inode number 2). + +*subvolid-resolve* <subvolid> <path>:: +Get file system paths for the given subvolume ID. + +EXIT STATUS +----------- +*btrfs inspect-internal* returns a zero exit status if it succeeds.
