I would always use the -r flag on lvreduce and get the filesystem reduction AND logical volume reduction done in one step. I'm not familiar with vfat, so it might not apply. You would at least need to specify the type though as RudiC says.
Using the -r flag does the whole process, i.e. unmounts, reduces FS & LV and re-mounts, so:-
becomes just:-
I hope that this helps,

Hello everyone
I need to resize a filesystem /home I want to add 200mb and I have space on the disk with lsvg rootvg command I check this but I cant because has a mirror.

Hello,
I created a script that runs perfectly on 2 different account but I it will not run in 2 others (HP-UX).

Dear All,
We have HP Unix 11.31.
We have two VG, VG01 and VG02.
In VG01 there are three mount point each of 100gb size. There is no data on below mount point

lvreduce
LVREDUCE(8) System Manager's Manual LVREDUCE(8)NAME
lvreduce - reduce the size of a logical volume
SYNOPSIS
lvreduce [-A|--autobackup {y|n}] [-d|--debug] [-h|--help] [-t|--test] [-v|--verbose] [--version] [-f|--force] [--noudevsync] {-l|--extents
[-]LogicalExtentsNumber[%{VG|LV|FREE|ORIGIN}] | [-L|--size [-]LogicalVolumeSize[bBsSkKmMgGtTpPeE]} [-n|--nofsck] [-r|--resizefs] Logi-
calVolume{Name|Path}
DESCRIPTION
lvreduce allows you to reduce the size of a logical volume. Be careful when reducing a logical volume's size, because data in the reduced
part is lost!!!
You should therefore ensure that any filesystem on the volume is resized before running lvreduce so that the extents that are to be removed
are not in use.
Shrinking snapshot logical volumes (see lvcreate(8) for information to create snapshots) is supported as well. But to change the number of
copies in a mirrored logical volume use lvconvert(8).
Sizes will be rounded if necessary - for example, the volume size must be an exact number of extents and the size of a striped segment must
be a multiple of the number of stripes.
OPTIONS
See lvm(8) for common options.
-f, --force
Force size reduction without prompting even when it may cause data loss.
--noudevsync
Disable udev synchronisation. The process will not wait for notification from udev. It will continue irrespective of any possible
udev processing in the background. You should only use this if udev is not running or has rules that ignore the devices LVM2 cre-
ates.
-l, --extents [-]LogicalExtentsNumber[%{VG|LV|FREE|ORIGIN}]
Reduce or set the logical volume size in units of logical extents. With the - sign the value will be subtracted from the logical
volume's actual size and without it the value will be taken as an absolute size. The number can also be expressed as a percentage
of the total space in the Volume Group with the suffix %VG, relative to the existing size of the Logical Volume with the suffix %LV,
as a percentage of the remaining free space in the Volume Group with the suffix %FREE, or (for a snapshot) as a percentage of the
total space in the Origin Logical Volume with the suffix %ORIGIN. The resulting value for the substraction is rounded downward, for
the absolute size it is rounded upward.
-L, --size [-]LogicalVolumeSize[bBsSkKmMgGtTpPeE]
Reduce or set the logical volume size in units of megabytes. A size suffix of k for kilobyte, m for megabyte, g for gigabytes, t
for terabytes, p for petabytes or e for exabytes is optional. With the - sign the value will be subtracted from the logical vol-
ume's actual size and without it it will be taken as an absolute size.
-n, --nofsck
Do not perform fsck before resizing filesystem when filesystem requires it. You may need to use --force to proceed with this option.
-r, --resizefs
Resize underlying filesystem together with the logical volume using fsadm(8).
EXAMPLES
Reduce the size of logical volume lvol1 in volume group vg00 by 3 logical extents:
lvreduce -l -3 vg00/lvol1
