Internal Server Error in Fuel UI when adding nodes

[Nikolay Korshenin]

ENVIRONMENT
============
VirtualBox 4.2.16 r86992
5 VMs created by vbox-scripts-3.2.zip
Fuel from ISO image: fuel-3.2.1-73-2013-11-28_06-53-30.iso

TEST CASE
=========
1) Deploy OpenStack in simple (non-HA) mode with Centos
1 controller + 1 cinder + 1 compute
Neutron + GRE (eth0 - admin pxe, eth1 - public, eth2 - other )

2) Then remove the environment

3) And deploy on the same VMs new environmet :
HA-mode, Centos, 3 controllers + 1 cinder+ceph-osd + 1 compute+ceph-osd
Neutron + GRE (eth0 - admin pxe, eth1 - public, eth2 - other )

EXPECTED RESULT
===============
new env is successfully deployed

ACTUAL RESULT
=============
 Response code '500 Internal Server Error' when I tryed to add 3 nodes as controllers to new cloud env:
