Pre flight checks

  • Check all Ceph pools are running on at least 2/3 replication
  • Check that all running VM's on the node you want to reboot are in HA (if not, add them or migrate them away manually)
  • Check that Ceph is healthy -> No remapped PG's, or degraded data redundancy

Reboot process

  • Start maintenance mode for the Proxmox node and any containers running on the node
  • Start maintenance mode for Ceph, specify that we only want to surpress the trigger for health state being in warning by setting tag `ceph_health` equals `warning`
  • Set noout flag on host: `ceph osd set-group noout <node>`
  • Reboot node through web GUI
  • Wait for node to come back up
  • Wait for OSD's to be back online
  • Remove noout flag on host: `ceph osd unset-group noout <node>`
  • Ackowledge triggers
  • Remove maintenance modes
