Step 6. Increase the physical volume size of the VDO volume:
# # vvd do o g grro ow wP Ph hyyssiiccaall ----n naam mee= =vvd do 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 dm msseettu up p ttaab bllee vvd do o__d daattaa
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.
