For those interested, here's the man page for resize2fs, expalining how
to use it:
resize2fs - ext2 file system resizer
resize2fs [ -d debug-flags ] [ -f ] [ -F ] [ -p ] device [
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 par-
titions. 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! Other-
wise, 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!
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
