[CentOS-devel] Corosync/Pacemaker mess after upgrade to 6.4

i've been using Corosync (with Pacemaker) for my production HA iscsi
Upon upgrading to CentOS 6.4, the upgraded node will not join the
cluster. It might also be a bug within pacemaker code, but i'm not sure.
There is also crm command missing (i know i can get in from suse repo).
I saw the RH's 6.4 technical notes:
where they suggest we move to cman.
Because the upgrade brakes working cluster with corosync/pacemaker
setup, i would like to propose, that we add this into to release notes
for CentOS 6.4.
I'm also thinking about the best way to get fully working cluster back.
All suggestions are welcome. Please note that we must not stop currently
Is it possible, that there is a bug in new pacemaker (1.1.8-7.el6) and
it won't work with old pacemaker (1.1.7-6.el6) or are they just
incompatible be default? (Nodes after upgrade don't see each other.)
I also wonder, will corosync be removed in future RH 6.* releases and
should i move over to cman?
