[Pacemaker] problem with pacemaker/corosync on CentOS 6.3

[fatcharly at gmx.de]

Hi,

I´m using a pacemaker+corosync bundle to run a pound based loadbalancer. After an update on CentOS 6.3 there is some mismatch of the node status. Via crm_mon on one node eveything looks fine while on the other node everything is offline. Everything was fine on CentOS 6.2.

Node powerpound:
