No fencing wouldn't be helping.
And it looks like drbd resources are hanging, not pacemaker/corosync.

All are working well during testing (I restarted the vms alternately), but after a day when I kill the other node, I always end up corosync and pacemaker hangs on the surviving node. Date and time on the vms are in sync, I use unicast, tcpdump shows both nodes exchanges, confirmed that DRBD is healthy and crm_mon show good status before I kill the other node. Below are my configurations and versions I used:
