Hi,
I've got ovirt running on a single host (with hosted-engine). I just upgraded the engine from 4.0.4 to 4.0.5. That was pretty easy; I just put the system into global maintenance mode, then yum update, then engine-setup, then took the host out of maint mode. Easy peasy.
'took the host out of maint' -> took the engine VM out of maintenance mode: global maintenance mode means that ovirt-ha-agent (on any hosts) will not try to check, restart, migrate... the engine VM.
Now, I want to update the host itself. Since it's a single host system I know I'll need to shut down all the VMs (because there's no place to migrate them). This means I'll need to shut down the engine VM, too. That would imply that I can't use the "Update" feature from the ui, right?
Yes, correct
So what IS the process to properly update a single-host host? My guess is:
* shutdown all the VMs
* go into global maint mode (what IS the difference between global and
local?) * shutdown the engine/engine VM * yum update on the host * restart services (or reboot, I guess) * bring the system out of maintenance mode
shutdown or hibernate all the other VMs. set global maintenance mode to avoid ovirt-ha-agent trying to restart the engine vm shutdown the engine VM (from the host CLI) with hosted-engine --vm-shutdown yum update restart services bring the system out of global maintenance mode: in a couple of minutes the HA agent should restart the engine VM
Am I missing a step? Do I need to run hosted-engine --deploy again similar to how I needed to run "engine-setup" on the engine? Or is there something else I need to run?
Thanks,
