[PVE-User] cluster node issue after upgrade (1.3 -> 1.5)

Hi Gwenn,

You said previously that you had an iscsi storage connected to the 
nodes. Is it connected directly to all the nodes, and is open-iscsi 
installed on all the nodes ?
# dpkg -l |grep open-iscsi
ii  open-iscsi                        2.0.870~rc3-0.4.1        High 
performance, transport independent iSCS

I had previously such errors. One was due to the fact that one node was 
not directly connected to the iscsci storage, so it could not share the 
iscsi storage listed in teh web GUI (so synchronization errors and bad 
thing for the whole behavior of the cluster).

Another issue I had is that open-iscsi is not installed by default when 
you upgrade a node. You have to install the package yourself....
It is only installed on a fresh install...
