.SH DESCRIPTION
|
|
|
|
The
|
1997-06-17 07:52:12 +04:00
|
|
|
.B resize2fs
|
1997-06-08 00:42:58 +04:00
|
|
|
program will resize ext2 file systems. It can be used to enlarge or
|
1998-02-21 07:20:44 +03:00
|
|
|
shrink an ext2 file system located on
|
|
|
|
.I device
|
|
|
|
so that it will have
|
1997-06-17 07:52:12 +04:00
|
|
|
.I size
|
|
|
|
blocks.
|
1998-02-21 07:20:44 +03:00
|
|
|
If the
|
|
|
|
.I size
|
|
|
|
parameter is not specified, it will default to the size of the partition.
|
|
|
|
The
|
|
|
|
.I size
|
|
|
|
parameter may never be larger than the size of the partition.
|
|
|
|
.PP
|
|
|
|
The
|
|
|
|
.B 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
|
|
|
|
.BR 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.
|
|
|
|
.PP
|
|
|
|
If you wish to shrink the an ext2 partition, first use
|
|
|
|
.B resize2fs
|
|
|
|
to shrink the size of filesystem. Then you may use
|
|
|
|
.BR 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!

.I \-d debug-flags
|
1998-02-21 07:20:44 +03:00
|
|
|
Turns on various resize2fs debugging features, if they have been compiled
|
|
|
|
into the binary.
|
1997-06-17 07:52:12 +04:00
|
|
|
.I debug-flags
|
|
|
|
should be computed by adding the numbers of the desired features
|
|
|
|
from the following list:
|
|
|
|
.br
|
|
|
|
\ 1\ \-\ Print out all disk I/O
|
|
|
|
.br
|
|
|
|
\ 2\ \-\ Debug block relocations
|
|
|
|
.br
|
|
|
|
\ 8\ \-\ Debug inode relocations
|
|
|
|
.br
|
|
|
|
\ 16\ \-\ Debug moving the inode table
|
|
|
|
.TP
|
|
|
|
.I \-p
|
|
|
|
Prints out a percentage completion bars for each
|
|
|
|
.B resize2fs
|
|
|
|
operation, so that the user can keep track of what
|
|
|
|
the program is doing.
|
|
|
|
.TP
|
1998-02-21 07:20:44 +03:00
|
|
|
.I \-f
|
|
|
|
Forces resize2fs to proceed with the filesystem resize operation, overriding
|
|
|
|
some safety checks which resize2fs normally enforces.
|
|
|
|
.TP
|
1997-06-17 07:52:12 +04:00
|
|
|
.I \-F
|
|
|
|
Flush the filesystem device's buffer caches before beginning. Only
|
|
|
|
really useful for doing
|
|
|
|
.B resize2fs
|
|
|
|
time trials.
