[Pacemaker] cman+qdisk+pacemaker - pacemaker qdisk node offline

Hey all, first time here.
Two node cluster
Centos 6.3 x86_64
cman-3.0.12.1-32.el6_3.2.x86_64
pacemaker-1.1.7-6.el6.x86_64
I have a two node cluster using qdisk. The 'three' nodes work great so
far, but I have an issue with pacemaker importing the qdisk as a node
and showing it offline. As a second issue, the qdisk device seems to
change after reboots causing pacemaker, when started, to import another
new qdisk name as an offline node.
Here are the examples:
$ cman_tool nodes
Node Sts Inc Joined Name
0 M 0 2012-12-13 09:50:58 /dev/block/8:176
1 M 1796 2012-12-13 09:50:46 node-1
3 M 1808 2012-12-13 10:31:59 node-2
now for the fun, crm_mon output: (as you will notice it has old
/dev/block/<ids> as offline nodes from previous starts)
$ crm_mon -V1

1) Is there any way to bring the real qdisk online?
2) Is there something I am missing to not import the qdisk as a node?
Thanks for the time!
