When you say 'a running lvm', I presume you mean that there is a logical volume that you wish to move and either the raw device is open by an application or database; or there is a mounted filesystem built on it. In either case the included tools should do the job for you, however there are a few rules to consider:-
The logical volume can only be moved within the volume group
Primary & secondary (even tertiary) copies logical partitions (LPs) may not share the same disk
Perhaps something else?
Can you share though output from:-
Are you adding space to your volume group at the same time, or is there space available? It would be good to know the target area you wish to move it to.

dmeventd
DMEVENTD(8) System Manager's Manual DMEVENTD(8)NAME
dmeventd - Device-mapper event daemon
SYNOPSIS
dmeventd [-d [-d [-d]]] [-f] [-h] [-R] [-V] [-?]
DESCRIPTION
dmeventd is the event monitoring daemon for device-mapper devices. Library plugins can register and carry out actions triggered when par-
ticular events occur.
LVM PLUGINS
Mirror Attempts to handle device failure automatically. See lvm.conf(5).
Raid Attempts to handle device failure automatically. See lvm.conf(5).
Snapshot
Monitors how full a snapshot is becoming and emits a warning to syslog when it exceeds 80% full. The warning is repeated when 85%,
90% and 95% of the snapshot is filled. See lvm.conf(5).
Thin Monitors how full a thin pool is becoming and emits a warning to syslog when it exceeds 80% full. The warning is repeated when 85%,
90% and 95% of the thin pool is filled. See lvm.conf(5).
OPTIONS -d Repeat from 1 to 3 times (-d, -dd, -ddd) to increase the detail of debug messages sent to syslog. Each extra d adds more debugging
information.
-f Don't fork, run in the foreground.
-h, -? Show help information.
-R Replace a running dmeventd instance. The running dmeventd must be version 2.02.77 or newer. The new dmeventd instance will obtain a
list of devices and events to monitor from the currently running daemon.
-V Show version of dmeventd.
