I suspect split-brain. Please check your kernel

Our local heartbeat/drbd cluster has been moody for the last few

been a few pages out of sync.
I check the Network link too, because some times the network are the
real problem.
Did you test the network interface?.
Did you change the the protocol to A for example.. and make more test.
In my experience the SSD disk has problems for broken.
Hi all,
I'm happy to announce a new tutorial!
https://alteeve.com/w/2-Node_Red_Hat_KVM_Cluster_Tutorial
This tutorial walks a user through the entire process of building a
2-Node cluster for making KVM virtual machines highly available. It uses
Red Hat Cluster services v3 and DRBD 8.3.12.
Hi,
DRBD 8.3.12 on CentOS 6.2; SDP from kernel-ib-1.5.3, built locally
from ofa_kernel-1.5.3-OFED srpm. DRBD resource config is as follows:
resource vg_cluster1 {
on alice {
device /dev/drbd1 minor 1;
disk /dev/sda;
address sdp
