This is a qustion of what is the best or right way to adding volumes to a
diskpool, specifically about "formatsize" option.

I have a primary diskpool which has 2X5GB volumes on 2 harddrives. Now I
have about 100GB free space ( 2 X 50Gb harddrive ) I want to add to the
diskpool.

My question is:

a. Do I need to keep the formatsize the same as the existing volumes? Say,
specify 20 X 5GB volumes and add to the pool?

b. If say no to question a. Do I better to create 10 X 10GB volumes or 2 X
50Gb volumes? does that affect performance if the the volumes are on
different HDs?

c. Just with to confirm the command to do so is:

def vol <stgpool-name> <file-in-partision> formatsize=<mb>


Thanks in advance for your advice
