Ok, so I have reinstalled everything and have a clean setup. However,
it still ain't workin unfortunately. Can you explain how I'm supposed
to use unique_clone_address? This is mentioned at the start of the
thread but not with the command. I tried doing what you suggest here:

# primitive ClusterIP.144.1 ocf:heartbeat:IPaddr2 params
ip="10.144.1.1" cidr_netmask="32" clusterip_hash="sourceip" op monitor
interval="120s"
# clone CloneIP ClusterIP.144.1 meta globally-unique="true" clone-max="8"

That gave:

[root at FW1 ~]# crm status

Online: [ FW1 FW2 ]

 Clone Set: CloneIP.144.1 [ClusterIP.144.1] (unique)
     ClusterIP.144.1:0  (ocf::heartbeat:IPaddr2):       Started FW1
     ClusterIP.144.1:1  (ocf::heartbeat:IPaddr2):       Started FW2
     ClusterIP.144.1:2  (ocf::heartbeat:IPaddr2):       Stopped
     ClusterIP.144.1:3  (ocf::heartbeat:IPaddr2):       Stopped
     ClusterIP.144.1:4  (ocf::heartbeat:IPaddr2):       Stopped
     ClusterIP.144.1:5  (ocf::heartbeat:IPaddr2):       Stopped
     ClusterIP.144.1:6  (ocf::heartbeat:IPaddr2):       Stopped
     ClusterIP.144.1:7  (ocf::heartbeat:IPaddr2):       Stopped

But none of the IPs were pingable after running the clone (just with
the primitive it was ok).
doing:
crm(live)# configure property stop-all-resources=false
Didn't get the other IPs "Started".

So I got rid of this (successfully) and tried:

primitive ClusterIP.144.1 ocf:heartbeat:IPaddr2 params ip="10.144.1.1"
cidr_netmask="32" clusterip_hash="sourceip"
unique_clone_address="true" op monitor interval="120s"

But now I have:

crm(live)#  status

(unmanaged) FAILED

Failed actions:

And I can't delete it:
crm(live)# configure property stop-all-resources=true
crm(live)# configure commit
INFO: apparently there is nothing to commit
INFO: try changing something first
crm(live)# configure erase
WARNING: resource ClusterIP.144.1 is running, can't delete it
ERROR: CIB erase aborted (nothing was deleted)

I can't work out how to move forward... Any pointers?
