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.

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] [-f|--force] [-h|--help] {-l|--extents [-]LogicalExtentsNumber| -L|--size [-]LogicalVolume-
Size[kKmMgGtT]} [-v|--verbose] LogicalVolumePath
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 the (eg) filesystem on the volume is resized running lvreduce so that the extents that are to be removed
are not in use. If the filesystem is ext2 then you can use the e2fsadm(8) command to both resize the filesystem and the logical volume
together. Shrinking snapshot logical volumes (see lvcreate(8) for information to create snapshots) is supported as well.
OPTIONS
-A, --autobackup y/n
Controls automatic backup of VG metadata after the change ( see vgcfgbackup(8) ). Default is yes.
-d, --debug
Enables additional debugging output (if compiled with DEBUG).
-f, --force
Force size reduction without any question.
-h, --help
Print a usage message on standard output and exit successfully.
-l, --extents [-]LogicalExtentsNumber
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 will be taken as an absolute size.
-L, --size [-]LogicalVolumeSize[kKmMgGtT]
Reduce or set the logical volume size in units of megabyte by default. A size suffix of k for kilobyte, m for megabyte, g for giga-
byte or t for terabyte is optional. With the - sign the value will be subtracted from the logical volume's actual size and without
it the will be taken as an absolute size.
-v, --verbose
Gives verbose runtime information about lvreduce's activities.
Example
"lvreduce -l -3 /dev/vg00/lvol1" reduces the size of logical volume lvol1 in volume group vg00 by 3 logical extents.
DIAGNOSTICS
lvreduce returns an exit code of 0 for success and > 0 for error:
1 no logical volume name on command line
2 invalid logical volume name
3 logical volume is not active
4 logical volume doesn't exist
5 error reading VGDA
6 error getting index of logical volume
7 new size of logical volume not smaller than old one
8 error setting VGDA up for reduce
9 error reducing logical volume in kernel
10 error writing VGDA to physical volume(s)
11 error getting index for read/write statistic transfer
12 error getting status of logical volume from kernel
13 error setting up copy on write exception table
95 driver/module not in kernel
96 invalid I/O protocol version
97 error locking logical volume manager
98 invalid lvmtab (run vgscan(8))
99 invalid command line
ENVIRONMENT VARIABLES
LVM_AUTOBACKUP
If this variable is set to "no" then the automatic backup of VG metadata is turned off.
LVM_VG_MAX_BACKUPS
This variable determins the backup history depth of kept VGDA copy files in /etc/lvmconf. It can be set to a positive number between
0 and 999. The higher this number is the more steps are you able to backup with vgcfgrestore(8) from the changes you make to your
volume groups.
LVM_VG_NAME
The default Volume Group Name to use. Setting this variable enables you to enter just the Logical Volume Name rather than its com-
plete path.
