[Linux-cluster] porblem with quorum at cluster boot

hello,
I have a 2 node cluster with qdisk quorum partition;
each node has 1 vote and the qdisk has 1 vote too; in cluster.conf I
have this explicit declaration:
<cman expected_votes="3" two_node="0"\>
when I have both 2 nodes active cman_tool status tell me this:
Version: 6.1.0
Nodes: 2
Expected votes: 3
Quorum device votes: 1
Total votes: 3
Node votes: 1
Quorum: 2
then, if I power off a node these value, as expected, changed this way:
Nodes: 1
Total votes: 2
and the cluster is still quorate and functional.
the problem is if I power off both the node and them power on only one
of them: in this case the single node does not quorate and the cluster
does not start: I have to power on both the node to have the cluster
(and services on the cluster) working.
I'd like the cluster can work (and boot) even with a single node (ie, if
one of the node has hw failure and is down I still want to be able to
reboot the working node and have it booting correctly the cluster)
any hints? (thank's for reading all this)
