I just had the same problem. 
My <unknown> error indeed to the fact that glusterd / glusterfsd were
not running.

After starting them it turned out the host setup did not automatically
add the iptables rules for gluster. I added to iptables:

# gluster
-A INPUT -p tcp --dport 24007:24011 -j ACCEPT
-A INPUT -p tcp --dport 38465:38485 -j ACCEPT

Afterwards 'gluster peer status' worked and my host was operational
again.

Hint: Sometimes this is do to gluster itself. Restaring glusterd works
most of the time to fix this.
