.SH DESCRIPTION
.
fsadm utility checks or resizes the filesystem on a device (can be
also dm-crypt encrypted device).
It tries to use the same API for
.BR ext2 ,
.BR ext3 ,
.BR ext4 ,
.BR ReiserFS
and
.BR XFS
filesystem.
.
.SH OPTIONS
.
.TP
.BR -e | --ext-offline
Unmount ext2/ext3/ext4 filesystem before doing resize.
.
.TP
.BR -f | --force
Bypass some sanity checks.
.
.TP
.BR -h | --help
Display the help text.
.
.TP
.BR -l | --lvresize
Resize also given lvm2 logical volume. More volume management
functionality is provided with complementary \fBlvresize\fP(8) and the option
.BR -r | --resizefs.
.
.TP
.BR -n | --dry-run
Print commands without running them.
.
.TP
.BR -v | --verbose
Be more verbose.
.
.TP
.BR -y | --yes
Answer "yes" at any prompts.
.
.TP
.BR -c | --cryptresize
Resize dm-crypt mapping together with filesystem detected on the device. The dm-crypt device must be recognizable by cryptsetup(8).
.
.TP
.BR \fInew_size [ B | K | M | G | T | P | E ]
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'.

.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.
