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



I'm just starting out using LVM under SuSE 7.0. I created a logical
volume which was initially 30Gb but I then resized it to 90Gb (using
lvresize) spanning 3 physical volumes each of 30Gb.

Now, lvdisplay/vgdisplay shows the LV/VG size as 90Gb, but df still
lists the file system as 30Gb.

How can I get df to recognise the addtional space ?

Thanks in advance
