NAME

       resize2fs - ext2/ext3 file system resizer

SYNOPSIS

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

DESCRIPTION

       The resize2fs program will resize ext2 file systems.  It can be used to
       enlarge or shrink an ext2 file system  located  on  device.   The  size
       parameter  specifies  the  requested new size of the filesystem.  If no
       units are specified, the units of  the  size  parameter  shall  be  the
       filesystem blocksize of the filesystem.  Optionally, the size parameter
       may be suffixed by one of the following  the  units  designators:  ’s’,
       ’K’,  ’M’,  or  ’G’,  for  512  byte  sectors, kilobytes, megabytes, or
       gigabytes, respectively.  The size  of  the  filesystem  may  never  be
       larger  than  the  size  of  the  partition.   If size parameter is not
       specified, it will default to 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.   After  running fdisk(8), run resize2fs to resize the ext2
       filesystem to use all of the space in the newly enlarged partition.

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

OPTIONS

       -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.
