RESIZE2FS(8)                                                      RESIZE2FS(8)



NAME
       resize2fs - ext2 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 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 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 oper-
              ation,  so  that  the user can keep track of what the program is
              doing.

       -f     Forces resize2fs to proceed with the  filesystem  resize  opera-
              tion,  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.
