[linux-lvm] lvdisplay disagrees with df for resized LV

Andy,
The size of the LV and the size of the filesystem are two different
things. I have always found that after increasing the size of the LV I
still needed to resize the filesystem. Depending on what filesystem you
are using, look at /sbin/resize_reiserfs or /usr/sbin/ext2resize. That
should provide the result you are looking for.
