We have 22 braggi systems. The Ceph Foundation graciously purchased these late 2019/early 2020 to help reduce our reliance on ephemeral Jenkins slaves in OVH's Openstack public cloud.

There is an incredibly annoying race condition when installing CentOS 9 Stream on these nodes where sda and sdb get flip flopped. dgalloway tried fixing this with https://github.com/ceph/ceph-cm-ansible/pull/703/commits/1058a3d0ca85f00a0f7a2df416c4a22a2e08883c which did help but not entirely.

You can check if anaconda picked the right disk by pulling up the Java KVM, switching to another terminal (Ctrl+Alt+F2) and checking if /mnt/sysroot is on the 800GB or 400GB drive. You want it to be on the 400GB drive. If it's not, just reboot and try again.

1. Reimage using Cobbler
2. Once the OS install is done,
   1. Run the ceph-cm-ansible users role
   2. Run ansible-playbook common.yml --tags vars,nagios,monitoring-scripts --limit braggi##
   3. Run https://github.com/djgalloway/sepia/blob/master/ansible-playbooks/jenkins-build-home.yml
   4. Run https://github.com/ceph/ceph-build/blob/master/ansible/examples/slave.yml
      1. ansible-playbook -M ./library/ -e permanent=True slave.yml --extra-vars '{"labels": "amd64 XXXXX huge sepia x86_64 braggi gigantic"}' --extra-vars '{"token": "XXXXX", "jenkins_credentials_uuid": "jenkins-build", "api_uri": "https://jenkins.ceph.com"}' --limit braggiXX*
