Preparations

Before starting the upgrades you should realle make sure you run the cluster with octupus features:

# ceph osd dump | grep require_osd_release
require_osd_release nautilus
# ceph osd require-osd-release octopus
# ceph osd dump | grep require_osd_release
require_osd_release octopus

Also make sure that all your OSD's are bluestore as filestore is deprecated in Quincy:

root@cephmon1:~# ceph osd metadata | grep osd_objectstore | sort | uniq -c
     27         "osd_objectstore": "bluestore",

Starting the upgrade

To start the upgrade you should:

• Set the following key in hiera:
  • ceph::params::release: 'quincy'
• Check out the ceph-Q related puppet-env.

Monitors

• apt-get dist-upgrade the ceph-mons
  • Restart ceph-mon services as you go.

Storage-nodes

Quincy needs 20.04 or newer; so if your storage-nodes are 18.04 you should plan for a reinstallation of them.

• Upgrade storage-nodes
  
  • Restart ceph-osd's on one node at a time.
• When all storage-nodes are upgraded you can run:
  • ceph osd require-osd-release quincy

Clients

• Upgrade radosgw's
  • Reboot the radsgw's afterwards.
• Upgrade compute-nodes
  • Reboot the compute-nodes afterwards to make sure all VM's use the new client.
