Description of problem: In upgrading RHCS documentation, it needs to be explicitly mention to finalize the process as last step - "a VM restart or live-migration is *necessary* to get the new ceph-version running and it is not enough to only update the ceph-packages" Version-Release number of selected component (if applicable): After upgrading from one version to other version. How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: To finalize the upgrading steps, it is needful to mention as a last step that - "a client VMs a VM restart or live-migration is necessary to get the new ceph-version running and it is not enough to only update the ceph-packages". The reason is - For the VM/qemu to use the newer librbd/ceph that were just upgraded,a live-migration or rebooting VMs is necessary. The upgrading doc needs changes such as : https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/2/html/installation_guide_for_ubuntu/upgrading_ceph_storage_cluster
Updating the QA Contact to a Hemant. Hemant will be rerouting them to the appropriate QE Associate. Regards, Giri
That doc is for RHCS 2 which is no longer supported. That said, I see the problem in "Upgrading a Ceph Client Node", [1] if you're using the ceph-client with qemu-kvm you need to restart the vm or do a live migration. In the RHCS 3 docs (which are still supported) we do cover this issue, in fact there is a note that the VMs must be stopped and started, not just restarted. [2] In the RHCS 4 docs (latest supported version) we don't have a section on upgrading ceph client nodes. We just have a general upgrading chapter. [3] It does mention that the ansible playbooks update the client nodes last. I will add a final step that says to restart any applications using the ceph client, like the one that is in the RHCS 3 docs [2]. 1) https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/2/html/installation_guide_for_ubuntu/upgrading_ceph_storage_cluster#upgrading_a_ceph_client_node 2) https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/3/html-single/installation_guide_for_red_hat_enterprise_linux/index#upgrading-a-ceph-client-node 3) https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/4/html-single/installation_guide/index#upgrading-a-red-hat-ceph-storage-cluster
