Well, looking at my syslog after mounting my lvol, I saw the following
msg -

"May  7 11:51:26 localhost kernel: EXT2-fs warning: mounting fs with
errors, running e2fsck is recommended"

I also saw previous errors which you asked about (lots of them) -

"itmap: Cannot read inode bitmap - block_group = 3, inode_bitmap = 98307
May  6 14:44:13 localhost kernel: attempt to access beyond end of
device...."

I have realised what my base problem is.... I have reduced the LV size,
but not reduced the Ext2 filesystem.  For some reason I thought that
resizing the LV was sufficient.  Looking further at the HOWTO, and other
web docs has enlightened me further.

It seems I will try to learn how to use teh e2fsadm util.  BTW one of
the utils seems to be commercial from Powerquest.  I have the v4 of
Partition Magic already.  I know it resizes ext2 filesystems, but as far
as I know needs to be run from within windows (it's been a long time
since I've used it last).  Are the utils such as e2fsadm sufficient /
good enough without the commercial PM util?
