Missed -l option in man page, although users should prefer lvresize -r when the also want to do a volume management, as there they can specify i.e. extents for allocation. Also mention dm-crypt support in command description.

.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
|

|
|
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

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'.
