Hello, As I said it in the previous thread, the 3 nodes are 3 identical KVM virtual machines running on the same physical host which have more than enough resources (48 CPU 256GB RAM Gbit network). I have also tried to move them to other physical servers but didn't help. I also run constant

Hi, It seems that your cluster has something wrong with connection between nodes. So no dlm message can be sent out. This may cause a node being fenced, thus to crash. Please check your network condition including switch, Ethernet HBA card, etc. Thanks, Changwei On 2017/11/28 18:07,
