As root Copy the filesystem in another one e.g.
cd /usr; find. -print| cpio -dpuml /<backup-copy-filesystem>
Ah but you did an extendfs...
So when you say you have plenty of space on another filesytem do you mean you have no more free PE ?
Which case you will have to do the above to where you have room:
cd /;
find usr -depth|cpio -xdump /<where you can spare the space>
umount /dev/vg00/lvol7;
I imagine now you have not much choice:
rmdir /usr
ln -s /<where you copied usr> /usr

And now test!!

If all is fine and works
You will have to remove the logical volume and recreate it then do the copy the other way round by mounting lvol7 on lets say /usr2 in order to do the transfer then remove the link and mount lvol7 on /usr (dont forget the mkdir...)

Good luck

NAME
       lvremove - remove a logical volume

SYNOPSIS
       lvremove  [-A|--autobackup  {y|n}]  [-d|--debug] [-h|--help] [-t|--test] [-v|--verbose] [--version] [-f|--force] [--noudevsync] LogicalVol-
       ume{Name|Path} [LogicalVolume{Name|Path}...]

DESCRIPTION
       lvremove removes one or more logical volumes.  Confirmation will be requested before  deactivating  any	active	logical  volume  prior	to
       removal.   Logical  volumes  cannot be deactivated or removed while they are open (e.g. if they contain a mounted filesystem).  Removing an
       origin logical volume will also remove all dependent snapshots.

       If the logical volume is clustered then it must be deactivated on all nodes in the cluster before it can be removed. A single lvchange com-
       mand issued from one node can do this.

OPTIONS
       See lvm(8) for common options.

       -f, --force
	      Remove active logical volumes without confirmation.

       --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.

EXAMPLES
       Remove the active logical volume lvol1 in volume group vg00 without asking for confirmation:

       lvremove -f vg00/lvol1

       Remove all logical volumes in volume group vg00:

       lvremove vg00
