GlusterFS Add a New Server to the Pool

I have a GlusterFS set up with 2 volumes. I want to limit the size of the volume.  Right now it just takes up all the space it can get its hands on.

Looking at a client that has the two drives mounted.

I can see that one is 16TB and the other is 5.9TB
how can I limit this?

GlusterFS Add a New Server to the Pool

I have a GlusterFS set up with 2 volumes. One Volume is Replicated and one is Dispered.   See the following diagram

Its set up roughly like this.

I want to add one new fresh Gluster Server to the Pool and update the two volumes.  I want the Replicated to be Distributed Replicated volume and the Dispersed to remain the same type but add one more brick on the new server to it. see https://docs.gluster.org/en/latest/Quick-Start-Guide/Architecture/#types-of-volumes [1] for details on volume types.

Also see this diagram for what I am trying to move to.

 

GlusterFS Replacing a Server

GlusterFS Health

How do I determine the health of my glusterFS cluster.  How do I determine the health of each volume I created within the GlusterFS cluster? I have a basic GlusterFS running with 3 GlusterFS machines. 

Its set up roughly like this.

 

I want to check the health of the mount from the client and the health of the GlusterFS itself.
