第9章 Upgrading an overcloud with director-deployed Ceph deployments
If your environment includes director-deployed Red Hat Ceph Storage deployments with or without hyperconverged infrastructure (HCI) nodes, you must upgrade your deployments to Red Hat Ceph Storage 5. With an upgrade to version 5, cephadm now manages Red Hat Ceph Storage instead of ceph-ansible.
If you are using the Red Hat Ceph Storage Object Gateway (RGW), ensure that all RGW pools have the application label rgw as described in Why are the RGW services crashing after running the cephadm adoption playbook?.
Implementing this configuration change addresses a common issue encountered when upgrading from Red Hat Ceph Storage Release 4 to 5.
9.1. Installing ceph-ansible
If you deployed Red Hat Ceph Storage using director, you must complete this procedure. The ceph-ansible package is required to upgrade Red Hat Ceph Storage with Red Hat OpenStack Platform.
Procedure
Enable the Ceph 5 Tools repository:
[stack@director ~]$ sudo subscription-manager repos --enable=rhceph-5-tools-for-rhel-8-x86_64-rpmsInstall the
ceph-ansiblepackage:[stack@director ~]$ sudo dnf install -y ceph-ansible
