Next time, also indicate which node is DC; it helps to pick the right log ;-) Quite a lot of systemd and SSH connections IMHO... At 13:58:27 node1 (kvm03-node01.avigol-gcs.dk) seems gone. Thus (I guess): Jan 04 13:59:03 kvm03-node02 stonith-ng[28902]: notice: Requesting that kvm03-node03.avigol-gcs.dk perform 'reboot' action targeting kvm03-node01.avigol-gcs.dk Jan 04 13:59:22 kvm03-node02 crmd[28906]: notice: Peer kvm03-node01.avigol-gcs.dk was terminated (reboot) by kvm03-node03.avigol-gcs.dk on behalf of stonith-api.33494: OK Maybe your network was flooded during migration of VMs?: Jan 04 13:58:33 kvm03-node03 corosync[37794]: [TOTEM ] Retransmit List: 1 2 You can limit the number of simultaneous migrations, BTW.
