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 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
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!
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
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
-f Forces resize2fs to proceed with the filesystem resize operation,
overriding some safety checks which resize2fs normally
-F Flush the filesystem device's buffer caches before beginning.
Only really useful for doing resize2fs time trials.
