NAME
       fallocate - preallocate space to a file.

SYNOPSIS
       fallocate [-n] [-o offset] -l length filename

DESCRIPTION
       fallocate  is  used  to  preallocate blocks to a file.  For filesystems
       which support the fallocate system call, this is done quickly by  allo-
       cating blocks and marking them as uninitialized, requiring no IO to the
       data blocks.  This is much faster than creating a file  by  filling  it
       with zeros.

       As  of the Linux Kernel v2.6.31, the fallocate system call is supported
       by the btrfs, ext4, ocfs2, and xfs filesystems.

       The exit code returned by fallocate is 0 on success and 1 on failure.

OPTIONS
       -h, --help
              Print help and exit.

       -n, --keep-size
              Do not modify the apparent length of the file. This  may  effec-
              tively  allocate  blocks  past  EOF, which can be removed with a
              truncate.

       -o, --offset offset
              Specifies the beginning offset  of  the  allocation,  in  bytes.
              Suffixes  of  k,  m,  g, t, p, e may be specified to denote KiB,
              MiB, GiB, etc.

       -l, --length length
              Specifies the length of the allocation, in bytes.   Suffixes  of
              k,  m, g, t, p, e may be specified to denote KiB, MiB, GiB, etc.
