       resize2fs - ext2 file system resizer

       resize2fs [ -d debug-flags ] [ -f ] [ -F ] [ -p ] device [ size ]

       The  resize2fs program will resize ext2 file systems.  It can be used to enlarge or shrink
       an ext2 file system located on device so that it will  have  size  blocks.   If	the  size
       parameter is not specified, it will default to the size of the partition.  The size param-
       eter may never be larger than the size of the partition.

       The resize2fs program does not manipulate the size of partitions.  If you wish to  enlarge
       a filesystem, you must first make sure you can expand the size of the underlying partition
       first.  This can be done using fdisk(8) by deleting the partition and recreating it with a
       larger  size.  When recreating the partition, make sure you create it with the same start-
       ing disk cylinder as before!  Otherwise, the resize operation will certainly not work, and
       you may lose your entire filesystem.

       If  you	wish  to  shrink  an  ext2  partition,	first use resize2fs to shrink the size of
       filesystem.  Then you may use fdisk(8) to shrink the size of the partition.  When  shrink-
       ing  the  size of the partition, make sure you do not make it smaller than the new size of
       the ext2 filesystem!

       -d debug-flags
	      Turns on various resize2fs debugging features, if they have been compiled into  the
	      binary.	debug-flags  should be computed by adding the numbers of the desired fea-
	      tures from the following list:
		   1	- Print out all disk I/O
		   2	- Debug block relocations
		   8	- Debug inode relocations
		   16	- Debug moving the inode table

       -p     Prints out a percentage completion bars for each resize2fs operation, so	that  the
	      user can keep track of what the program is doing.

       -f     Forces  resize2fs  to proceed with the filesystem resize operation, overriding some
	      safety checks which resize2fs normally enforces.

       -F     Flush the filesystem device's buffer caches before beginning.  Only  really  useful
	      for doing resize2fs time trials.
