In ceph-10.2.6, the ceph init script uses systemd-run to launch ceph-mon and ceph-osd services. This generates transient systemd service files with basic configuration. On node shutdown, ceph is getting shutdown while it is still in use by containers, and without unmapping the RBD devices, causing the libceph kernel module to hang trying to communicate with the ceph monitor. This update patches the ceph init script to generate systemd overrides config files for the ceph-mon and ceph-osd that provide improved ordering during shutdown, as well as a script to run as part of the docker.service shutdown (by packaging a systemd override) to unmap the RBD devices. This ordering ensures kubelet and docker services are shutdown first, then the RBD devices are cleaned up, followed by the shutdown of the ceph services and service management (SM). Once kubelet and docker have shut down, the ceph-preshutdown.sh script is able to cleanly unmount and unmap the RBD devices and unload the rbd and libceph kernel modules. In ceph-11.0.1, the use of systemd-run was replaced with proper systemd service configuration files. Once ceph is upgraded for StarlingX, the ordering and cleanup will need to be revisited.
