How to extend a logical volume under linux (centos 4.4)

Hi all,

Using ACU on our DL380 G3 with Smart Array 5i controller, we added a new physical disk to a RAID 5 array and then successfully increased the logical disk to its maximum size (69443 MB).

However, since LVM still reports a much lower capacity and no space available for extension, we are wondering what we are missing here.

Thanks
