[linux-lvm] ext2resize error

["Jonathan S. Polacheck" <JPolache texasmutual com>]

I have a Mandrake Linux 8.1 system with a 2.4.8 kernel.  My logical volumes
include /usr, /var and /home (not / or /boot).  I originally set up all
lv(s) as ext3, which seemed to preclude the ext2_online patch.  My
/dev/sys/usr lv shows 2.44 gig in lvdisplay.  My one PV shows 3616 free
PEs.  df shows /usr to be 2,015,824 (k) and 96% utilized.  I run telinit 1
then umount -a.  /usr unmounts.  I then run ext2resize /dev/sys/usr.  It
returns "Your filesystem is too occupied to resize it to 16000 bytes."

Any suggestions?
