E2fsprogs contains e2fsck (used torepair filesystem inconsistencies after an unclean shutdown), mke2fs(used to initialize a partition to contain an empty ext2 filesystem),debugfs (used to examine the internal structure of a filesystem, tomanually repair a corrupted filesystem, or to create test cases fore2fsck), tune2fs (used to modify filesystem parameters), and most ofthe other core ext2fs filesystem utilities.You should install the e2fsprogs package if you need to manage theperformance of an ext2

       RESIZE2FS(8)NAME       resize2fs - ext2 file system resizerSYNOPSIS       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.AUTHOR       resize2fs was written by Theodore Ts'o .COPYRIGHT       Resize2fs  is Copyright 1998 by Theodore Ts'o and PowerQuest, Inc.
