Gluster users - Oct 2016 - How do I increase volume space on a gluster disperse volume

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?

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

Yes the command is like that.

You don't want to do that, 20TB from 40TB is wasted. Bricks should be same
size.
