(In reply to Marius Cornea from comment #0) > There are multiple issues here as I can tell, maybe not all of them strictly > related to the upgrade process but we can split them into multiple BZs if > needed. > > 1. ceph-ansible gets triggered when a node removal is requested.

An optimization could be made where what's to be done is discovered and it could be decided that ceph-ansible doesn't run but doing that is difficult. Running the correct playbook however _should_be_ idempotent so I think it better to focus on ensuring idempotence. > 2.

The compute node that is left over (24.14 as per `nova list` above) is the only client node in the inventory, which is right: [root@undercloud-0 ansible-mistral-actiondh26qI]# grep clients -A 5 inventory.yaml clients: hosts: 192.168.24.14: {} mdss: hosts: {} mgrs: [root@undercloud-0 ansible-mistral-actiondh26qI]# but, as you say, the wrong playbook, rolling_update.yml ran: [root@undercloud-0 ansible-mistral-actiondh26qI]# grep ansible-playbook ansible-playbook-command.sh ansible-playbook -vv /usr/share/ceph-ansible/infrastructure-playbooks/rolling_update.yml --user tripleo-admin --become --become-user root --extra-vars {"ireallymeanit": "yes"} --inventory-file /tmp/ansible-mistral-actiondh26qI/inventory.yaml --private-key /tmp/ansible-mistral-actiondh26qI/ssh_private_key --skip-tags package-install,with_pkg "$@" [root@undercloud-0 ansible-mistral-actiondh26qI]# That playbook that was used in the FFU and seems to be "left over" which is a problem. One way to address it is to document that the user needs to run the node deletion using something like: openstack overcloud node delete --stack QualtiyEng 0c2ceb6a-1648-44e2-9e27-3e10b50b8685 -e foo.yaml where foo.yaml contains the correct playbook: CephAnsiblePlaybook: ['/usr/share/ceph-ansible/site-docker.yml.sample'] The above could be used as a workaround in the meantime if you want to try it. Giulio: Is there a better way to get the stack to "remember" the right playbook? > 3. Nevertheless the ceph-ansible playbook should be idempotent and not fail, > from what I can tell from the log it fails on: > > "stderr": "Error EPERM: Are you SURE? Pool 'metrics' already has an enabled > application; pass --yes-i-really-mean-it to proceed anyway" This seems like an idempotence bug in ceph-ansible itself. I opened the following bug for it: https://bugzilla.redhat.com/show_bug.cgi?id=1562220 please triage this we are going through the list and assigning round robin thanks (DFG:Upgrades triage call) Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
