Does "mount -t glusterfs domU-12-31-39-00-A5-7B:PetShop /mnt/petshop" 
work any better?

 From 3.1 through 3.3, glusterd's management port is 24007/tcp and 
24008/tcp if you use rdma. Bricks (glusterfsd) use 24009 & up. (Deleted 
volumes do not reset this counter.) Additionally it will listen on 
38465-38467/tcp for nfs, also 38468 for NLM since 3.3.0. NFS also 
depends on rpcbind/portmap on port 111.

As long as the management port(s) are accessible, you should be able to 
get the rest of the port information through "gluster volume status".

Yes

Answered above.
