Upgrading the ceph cluster

ceph-ansible provides a playbook in infrastructure-playbooks for upgrading a Ceph cluster: rolling_update.yml.

This playbook could be used for both minor upgrades (X.Y to X.Z) or major upgrades (X to Y).

Before running a major upgrade you need to update the ceph-ansible version first.

example:

$ ansible-playbook -vv -i hosts infrastructure-playbooks/rolling_update.yml

Note

You can use the --limit flag with the rolling-update playbook to target a subset of OSDs or mons. For example:

ansible-playbook -vv -i hosts infrastructure-playbooks/rolling_update.yml \
   --limit mon1 --tags=mons
