So now you need to update all nodes to Pacemaker 1.1.8 but to avoid again issues with the next distribution update, I prefer to use CMAN as recommended.
Generally, these precautions concern locking LVM metadata operations while running DRBD in ‘dual-primary' mode.

It automates activation of the newly created LVM resources on the shared storage, but still provides no locking mechanism suitable for a ‘dual-primary' DRBD operation. navigate here You can also follow the official documentation here.
The second thing we need to configure is the cluster engine (corosync). Configuration for cman resides in the /etc/cluster/cluster.conf file:
