Problem resizing ext2 filesystem on LVM

[Dave Wapstra]

Hi,

I'm having some problems resizing an ext2 partition on a LVM Logical Volume. 
The filesystem is currently approx. 
170GB, the LV is about 200GB.  Parted seems to resize fine, no error messages 
are given.  However, the filesystem  
is not resized and the size stays the same.

I've resize the filesystem this way before from ~140GB to ~170GB and that 
worked fine.  Using parted 1.4.13 or 
1.4.22 gives the same result.

Below is a log showing the process. This is on a Sun E450 running Linux 2.4.2.
