[linux-lvm] ext2resize error

resize2fs did the trick.  Here is the additional system information;

ext2resize -v -d;
ext2_resize_fs
ext2_shrink_fs

Can you run "ext2resize -v -d /dev/sys/usr" and send me the output?  If
that doesn't produce anything useful, you may also need to run
"strace ext2resize /dev/sys/user" as well.  What does /proc/partitions
say about /dev/sys/usr?

Cheers, Andreas
