Suji's blog: How to add a disk to LVM:

LVM

Quick Notes First:

Formatting the new Disk

Suppose the Disk is /dev/sdb, the second scsi disk,

   fdisk /dev/sdb

   create as many partitions as you need using command n

   Label them with command t as 8e for making it Linux LVM

   Write and Exit with the command w.

Format the partitions you require using mkfs command

   mkfs -t ext3 -c /dev/sdb1

LVM commands

   pvcreate /dev/sdb1

   vgextend VolGroup00 /dev/sdb1

   lvextend -L 15G /dev/VolGroup00/LogVol01 ;for extending LogVol to 15GB

   lvextend -L+1G /dev/VolGroup00/LogVol01 ;for adding one more GB to Logical Volume LogVol01

   ext2online /dev/VolGroup00/LogVol01 ;for resizing the Logical Volumes

Thats it finished

On Ubuntu Intrepid 8.10 you need to use resize2fs to resize the lvm.
