       resize2fs - ext2 file system resizer

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

       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 parameter 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 starting disk cylinder as before!	Otherwise, the	resize
       operation  will	certainly  not	work,  and  you  may  lose your entire
       filesystem.

       If you wish to shrink the 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 shrinking the size of the partition,  make
       sure  you do not make it smaller than the new size of the ext2 filesystem!

OPTIONS    [Toc]    [Back]

       -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 features  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.
