Well, maybe I should say Volume Group instead of filesystem. Here's what I did:

Created logical volume, made ext2 filesytem, extended logical volume)

[/root]# pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE   PV "/dev/sdb" of VG "ftp" [8.43 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/sdc" of VG "ftp" [8.43 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/sdd" of VG "ftp" [8.43 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/sde" of VG "ftp" [8.43 GB / 72 MB free]
pvscan -- total: 4 [33.74 GB] / in use: 4 [33.74 GB] / in no VG: 0 [0]

[/root]# ext2resize /dev/ftp/lvol1 33g
ext2resize v1.1.15 - 2000/08/08 for EXT2FS 0.5b
ext2resize: ext2_open: invalid superblock
ext2resize: can't open /dev/ftp/lvol1
[/root]# pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE   PV "/dev/sdb"   is associated to an unknown VG (run vgscan)
pvscan -- ACTIVE   PV "/dev/sdc"   is associated to an unknown VG (run vgscan)
pvscan -- ACTIVE   PV "/dev/sdd"   is associated to an unknown VG (run vgscan)
pvscan -- ACTIVE   PV "/dev/sde"   is associated to an unknown VG (run vgscan)
pvscan -- total: 4 [33.74 GB] / in use: 4 [33.74 GB] / in no VG: 0 [0]

Note: this output is edited, but does show the problem.  After this, I get 

vgcreate -- ERROR: VGDA in kernel and lvmtab are NOT consistent; please run vgscan

and have to do dd if=/dev/zero of=/dev/sd<x> to clear all the tables
and do a reboot to clean up the VGDA in the kernel

I'll give GNU parted a try.
