Hi, yesterday, we had maintenance day and wanted to upgrade our Ganeti clusters.
Our Ganeti clusters use KVM and libvirt. Clusters running with Debian/stretch were not affected whereas clusters running Debian/jessie failed reproducible when starting more than 2 Ganeti instances. First, we want to confirm this issue with linux-image-3.16.0-6-amd64. We saw DRBD errors in our logs like... drbdX: Discarding network configuration (X = Number of Ganeti instance) As a workaround, we did a downgrade to the previous Debian-kernel release and put it on hold: root# echo linux-image-3.16.0-5-amd64 hold | dpkg --set-selections root# echo linux-image-amd64 hold | dpkg --set-selections root# dpkg --get-selections | grep hold linux-image-3.16.0-5-amd64 hold linux-image-amd64 hold Hope this helps.
