Description of problem: My understanding is that there is a requirement for the librbd1 package to be installed on OSP compute nodes so that compute nodes have reference to the shared library for RBD when mounting Ceph volumes within guest instances. However, both the OSP 9 'Director Installation and Usage' guide and the OSP 9 'Upgrading Red Hat OpenStack Platform' guide only state in their respective repository requirements sections that 'rhel-7-server-rhceph-1.3-osd-rpms' is required 'for Ceph storage nodes': OSP 9 Director Installation and Usage - 2.5. Repository Requirements https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/9/html-single/director_installation_and_usage/#sect-Repository_Requirements OSP 9 Upgrading Red Hat OpenStack Platform - 1.2. Repository Requirements https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/9/html-single/upgrading_red_hat_openstack_platform/#sect-Repository_Requirements As a result, the 'rhel-7-server-rhceph-1.3-osd-rpms' repository would not be applied to compute nodes when that documentation is followed. Subsequently, librbd1 would not get updated on compute nodes, which would leave compute nodes potentially exposed to known, fixed issues within librbd1. Version-Release number of selected component (if applicable): OSP 9 Director Installation and Usage guide and the OSP 9 Upgrading Red Hat OpenStack Platform guide current versions (and potentially those documents in reference to later major releases). How reproducible: N/A. Steps to Reproduce: N/A. Actual results: OSP 9 Director Installation and Usage guide and the OSP 9 Upgrading Red Hat OpenStack Platform guide do not mention a requirement for the 'rhel-7-server-rhceph-1.3-osd-rpms' channel to be active on compute nodes, but librbd1 may be required on compute nodes when Ceph volumes are mounted on guest instances. Expected results: For the guides to include reference to the requirement outlined above.
Wouldn't it be better to modify this to use librbd1 from within following repo: Red Hat Enterprise Linux Server 7 x86_64 rhel-7-server-rhceph-1.3-tools-rpms As it is part of product: "Red Hat Enterprise Linux Server 7 x86_64".
Hi Paul, I have added the tools repo to the OSP9 doc: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/9/html-single/director_installation_and_usage/#sect-Repository_Requirements I have also modified the text for OSP10: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/10/html-single/director_installation_and_usage/#sect-Repository_Requirements I've modified it to say to add the repo to all nodes if you're deploying a Ceph cluster. My rationale is that there are also some non-Compute components that need this channel too (I remember hitting some issues with standalone Telemetry nodes using Ceph as a backend). How does it look to you now? Was there anything further required?
Hi Dan, Thank you that looks great. Can I please ask that the same change is applied to the OSP 9 and 10 upgrade documents also?: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/9/html-single/upgrading_red_hat_openstack_platform/#sect-Repository_Requirements https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/10/html-single/upgrading_red_hat_openstack_platform/#sect-Repository_Requirements Many thanks in advance, Paul.
Hi Paul, Consider it done: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/10/html-single/upgrading_red_hat_openstack_platform/#sect-Repository_Requirements https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/9/html-single/upgrading_red_hat_openstack_platform/#sect-Repository_Requirements Was there anything esle needed?
Thank you Dan, that is great. From a review of this Bugzilla, it is my understanding that all requirements have been met. As such, I am closing this Bugzilla as resolved. Many thanks again for your help. Kind regards, Paul.
