As I have written earlier, the Samba server cannot be stopped since there may be a number of volumes that are exported, and it is undesirable to disturb I/O to/from the other volumes.
I agree that the lazy umount is not good in my case, since if I want to deallocate the resources used for the volume I unmounted, I have no idea when they will actually be free.
As I mentioned above, I am currently exploring the possibility to use "smbcontrol stop-share" to break the connection to the volume I want to umount, which should allow me to use normal umount after that.
I wonder if there is a better solution.
Latest news: I tested the smbcontrol solution integrated to our product and it works!
Thanks to all those who replied.

vgreduce
VGREDUCE(8) System Manager's Manual VGREDUCE(8)
NAME
vgreduce - reduce a volume group
SYNOPSIS
vgreduce [-a|--all] [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [--removemissing] [-t|--test] [-v|--verbose] VolumeGroupName [Physi-
calVolumePath...]
DESCRIPTION
vgreduce allows you to remove one or more unused physical volumes from a volume group.
OPTIONS
See lvm for common options.
-a, --all
Removes all empty physical volumes if none are given on command line.
--removemissing
Removes all missing physical volumes from the volume group, if there are no logical volumes allocated on those. This resumes normal
operation of the volume group (new logical volumes may again be created, changed and so on).
If this is not possible (there are logical volumes referencing the missing physical volumes) and you cannot or do not want to remove
them manually, you can run this option with --force to have vgreduce remove any partial LVs.
Any logical volumes and dependent snapshots that were partly on the missing disks get removed completely. This includes those parts
that lie on disks that are still present.
If your logical volumes spanned several disks including the ones that are lost, you might want to try to salvage data first by acti-
vating your logical volumes with --partial as described in lvm (8).
