resize2fs
RESIZE2FS(8) System Manager's Manual 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 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.
