NAME
       btrfstune - tune various btrfs filesystem parameters

SYNOPSIS
       btrfstune [options] <dev> [<dev>...]

DESCRIPTION
       btrfstune is used to tune various btrfs filesystem parameters,you can
       enable/disable some extended features for btrfs.

OPTIONS
       -S <value>
           Updates the seeding value. A positive value will enable seeding,
           zero will disable seeding, negtive is not allowed. Enable seeding
           forces a fs readonly so that you can use it to build other
           filesystems.

       -r
           Enable extended inode refs.

       -x
           Enable skinny metadata extent refs.

       -f
           Allow dangerous changes, e.g. clear the seeding flag

       When mounting the new device, btrfs will check whether the seeding flag
       is set when try to open seeding device. If the user clears the seeding
       flag of the seeding device, the new device will not be mountable. Even
       setting the seeding flag back will not fix this problem, because the
       generation will be changed at that time. Clear the seeding flag may
       damage the new filesystem.

EXIT STATUS
       btrfstune will return 0 if no error happened. If any problems happened,
       1 will be returned.
