.SH DESCRIPTION
.
fsadm utility checks or resizes the filesystem on a device.
It tries to use the same API for
.BR ext2 ,
.BR ext3 ,
.BR ext4 ,
.BR ReiserFS
.RB and
.BR XFS
filesystem.
.
.SH OPTIONS
.
.HP
.BR -e | --ext-offline
.br
Unmount ext2/ext3/ext4 filesystem before doing resize.
.
.HP
.BR -l | --lvresize
.br
Resize given device if it is LVM device.
.
.HP
.BR -f | --force
.br
Bypass some sanity checks.
.
.HP
.BR -h | --help
.br
Display the help text.
.
.HP
.BR -n | --dry-run
.br
Print commands without running them.
.
.HP
.BR -v | --verbose
.br
Be more verbose.
.
.HP
.BR -y | --yes
.br
Answer "yes" at any prompts.
.
.HP
.BR -c | --cryptresize
.br
Resize dm-crypt mapping together with filesystem detected on the device. The dm-crypt device must be recognizable by cryptsetup(8).
.
.HP
.BR \fInew_size [ B | K | M | G | T | P | E ]
.br
Absolute number of filesystem blocks to be in the filesystem,
or an absolute size using a suffix (in powers of 1024).
If new_size is not supplied, the whole device is used.
.
.SH DIAGNOSTICS
.
On successful completion, the status code is 0.
A status code of 2 indicates the operation was interrupted by the user.
A status code of 3 indicates the requested check operation could not be performed
because the filesystem is mounted and does not support an online
.BR fsck (8).
A status code of 1 is used for other failures.
.
.SH EXAMPLES
.
Resize the filesystem on logical volume \fI/dev/vg/test\fP to 1000 megabytes.
If \fI/dev/vg/test\fP contains ext2/ext3/ext4
filesystem it will be unmounted prior the resize.
All [y/n] questions will be answered 'y'.
.sp
.B fsadm -e -y resize /dev/vg/test 1000M
.
.SH ENVIRONMENT VARIABLES
.
.TP
.B "TMPDIR   "
The temporary directory name for mount points. Defaults to "\fI/tmp\fP".
.TP
.B DM_DEV_DIR
The device directory name.
Defaults to "\fI/dev\fP" and must be an absolute path.
