Yes the command is like that.
Besides, Can I have different size of the brick? Such as raid1,2,3 is 20 TB and raid5,6,7 is 40TB?
You don't want to do that, 20TB from 40TB is wasted. Bricks should be same size.
Similarly to my response to "Rebalancing after adding larger bricks", by
utilizing the cluster.min-free-disk setting (defaults to 10%) you can,
at least, ensure that your larger bricks are utilized as needed to
prevent over filling your smaller bricks should you choose to have
mismatched sizes.

Thanks, but what is the exact command to add-brick?
volume add-brick <VOLNAME> [<stripe|replica> <COUNT>] <NEW-BRICK> ...
Is it like
Gluster volume add-brick pdsclust raid1-gb:/data/gfs raid2-gb:/data/gfs raid3-gb:/data/gfs raid5-gb:/data/gfs raid6-gb:/data/gfs raid7-gb:/data/gfs
What is the value of > [<stripe|replica> <COUNT>]?

You would need to add 6 more bricks to the volume to get to this state.
