Upgrade Notes

ALL: this step happens on all servers

ONE: this step only happens on one server

Ceph Nautilus to Octopus

ALL: Change repo for Ceph

sudo sed -i 's/nautilus/octopus/' /etc/apt/sources.list.d/ceph.list

ONE: Set Ceph “noout” flag to prevent failover wackiness

sudo ceph osd set noout

ALL: Update Ceph via Apt

sudo apt-get update
sudo apt-get full-upgrade

ALL: Restart Ceph monitor daemon (one at a time, on all servers). Monitor the Ceph page in the Proxmox GUI and only restart a monitor daemon when all monitors are up.

sudo systemctl restart ceph-mon.target
