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 param-
eter 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 start-
ing 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 shrink-
ing 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 fea-
tures 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.
