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

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>]?

Besides, Can I have different size of the brick? Such as raid1,2,3 is 20 TB and
raid5,6,7 is 40TB?
