/etc/fstab 中最后两列值的含义

我只是想知道 /etc/fstab redhat linux 中最后两列的值。我有时会给出 1 2 或 0 0 但不确定它的真正含义。谁能解释一下。

复制出man fstab

The fifth field (fs_freq).
          This field is used by dump(8) to determine which filesystems need to be  dumped.   Defaults  to  zero
          (don't dump) if not present.

The sixth field (fs_passno).
          This  field  is  used  by  fsck(8) to determine the order in which filesystem checks are done at boot
          time.  The root filesystem should be specified with a fs_passno of 1.  Other filesystems should  have
          a  fs_passno  of 2.  Filesystems within a drive will be checked sequentially, but filesystems on dif‐
          ferent drives will be checked at the same time to utilize  parallelism  available  in  the  hardware.
          Defaults to zero (don't fsck) if not present.
