This role has been migrated to oVirt Ansible Collection, please use latest version from there. This repository is now readonly and no longer used for active development.

oVirt environment shutdown

The ovirt.shutdown_env role iterates through all the entities (vms and hosts) in an oVirt/RHV cluster and performs a clean and ordered shutdown. It also handles an Hosted-Engine and hyper-converged GlusterFS environment as a special case automatically detecting it. The role is intended to be run only against the engine machine. Please note that host shutdown is async and the playbook terminates before HE hosts are really down.

If on an Hosted-Engine environment, global maintenance mode will be set: the user has to manually exit it in order to get the engine VM automatically powered up once needed.

A startup mode is also available: in the startup mode the role will bring up all the power management configured hosts and it will unset the global maintenance mode if on an hosted-engine environment. The startup mode will be executed only if the 'startup' tag is applied; shutdown mode is the default. The startup mode requires the engine to be already up: power on it if it's a dedicated host, power on at least one of HE hosts (2 if on an hyperconverged env) and exit the global maintenance mode or manually start the engine VM with hosted-engine --vm-start

According to host power on order the engine could elect a new SPM host or reconstruct the master storage domain. The environment can take up to 10 minutes to come back to a stable condition. Possible improvements are tracked here: https://bugzilla.redhat.com/1609029
