Step 6. Increase the physical volume size of the VDO volume:
# # v v d d o o g g r r o o w w P P h h y y s s i i c c a a l l - - - - n n a a m m e e = = v v d d o o
Step 7. Increase the logical volume size to ten times the size of the physical volume:
a. Check the new size of the VDO data:
# # d d m m s s e e t t u u p p t t a a b b l l e e v v d d o o _ _ d d a a t t a a
0 18628986880 linear 9:124 2048
b. Calculate the new logical volume size according the following formula:
new logical volume size = (size of VDO data in 512–byte sectors) X (number bytes per sector)
X (relative size of the logical volume compared to the physical volume)
In our example, this becomes:
new logical volume size = 18,628,986,880 X 512 X 10 = 88,829,931,640,625 bytes or
approximately 88,829 GB.
