[Gluster-users] Question re Gluster peers , replication and redundancy

Couple of questions:

I have a gluster volume with two peers, 1 brick per peers, replication 2

The client is mounted via fuse using a vol file like this:

volume remote1
  type protocol/client
  option transport-type tcp
  option remote-host vnb.proxmox.softlog
  option remote-subvolume /mnt/data1/datastore1
volume remote2
  type protocol/client
  option transport-type tcp
  option remote-host vng.proxmox.softlog
  option remote-subvolume /mnt/data1/datastore1
volume replicate
  type cluster/replicate
  subvolumes remote1 remote2
volume writebehind
  type performance/write-behind
  option window-size 1MB
  subvolumes replicate
volume cache
  type performance/io-cache
  option cache-size 512MB
  subvolumes writebehind

If one of the peers (vnb or vng) goes down, the volume should still be 
available for reads and writes? thats my understanding of the reduncancy 

If I add a third peer (vnt.proxmox.softlog) that doesn't supply any bricks, 
does it help with the monitoring & quorum? or is it pointless?
