You could have done "vgcreate vg01 /dev/hda2 /dev/hdb2 /dev/hdd2" 
and skipped the vgextend calls.

You should have done the lvcreate command _after_ you have all 
the physical volumes in your volume group. Now you have to use 
lvextend to resize your logical volume. Run 

vgdisplay vg01 | grep "Total PE"

Check the reported Total PE number and use that in the next 
command

lvextend -l <PE number> lv01

Create a filesystem on the logical volume:

mke2fs -j /dev/vg01/lv01

Then mount it:

mount /dev/vg01/lv01 /drif

(You should move the mount point off the / directory to be FHS 
compliant)
