Packet loss at FRA3 Wednesday 3rd February 2021 05:00:07

We are experiencing packet loss at FRA3.

Additional hosts that needed a reboot after cluster recovery in order to stabilize them: gale, aegaeon, bus, tempel, autonoe, yeung, hyrrokkin, iapetus.

Performance is back to normal after full Ceph recovery.

A core switch has caused packet storms. After a reboot it worked fine again. Ceph performance will be degraded due to recovery processes. 6 VMs had to be rebooted (hernmann, kopff, scotti, ariel, pizarro, harpalyke).
