Software RAID 5 Resizing and LVM

I've been playing around with adding disks to a software RAID 5 array, and it works fine. However, i have LVM running over the top of that and i can't figure out how to enlarge the Phisical Volume to encompass the newly added capacity on the raid device. Has anyone achieved this at all?

Am I barking up the wrong tree here? If so, how would you go about adding drives to a software RAID 5 device, and actually adding the new space to the filesystem inside the RAID device?

Thanks in advance

Please look through the archive, just a couple of days ago there was a thread started about this topic (expanding a PV on a hardware raid).

Resizing the filesystem is completely LVM unrelated and depends on the actual filesystem used (resize2fs, resize_reiserfs, ...)
