#I have managed to configure 4 servers of beta dundee with glusterfs and ctdb and fully working ha without SPOF.
#I have four NICs: NIC0 management of xenserver 192.168.10.2*, NIC1 gluster vm client 192.168.10.14*, bond NIC2-3 10.10.10.1*, VIPs #from ctdb 192.168.10.13*. In /etc/hosts I keep only 10.10.10.1x server ips and use them in glusterfs volume creation and in #consequence in glusterfs backend traffic.
#The main compilation script:

#Removing local storage and configuring ctdb, /etc/hosts:
#http://pastebin.com/2Hez4MYN
#At the end you should:
#gluster peer probe servers
#and
#init_gluster4 "xenserverhw" "06" "08" "03" "04" "vol0" 4 #replica 4 at the end!
#create SR nfs and iso, make vm and install xen tools and enable ha with 3 failovers.

#Here are some screenshots of the glusterfs sr in the xenserver pool:
