I noticed this happens too, I think the issue is after N attempts the ovirt-ha-agent process will kill itself if it believes it can't access the storage or it fails in some other way. The ovirt-ha-broker service however still remains and continues to calculate the score. It'll be nice I guess if it could pro-actively restart the ha-agent every now and then. > > What is the supposed procedure after a shutdown (graceful / ungraceful) > of Hosted-Engine HA nodes?

I don't think any other VMs get restarted automatically, this is because the engine is used to ensure that the VM hasn't been restarted on another host. This is where power management etc comes into play. If all the nodes come up at the same time, in my testing, it took 10 minutes for the ha-agents to settle and then finally decide which host to bring up the engine. Then technically... (untested) any VMs which you've marked as HA should be automatically brought back up by the engine. This would be 15-20 minutes to recover which feels a little slow.. although fairly automatic. > > Thanks, > Daniel > > > > > > > _______________________________________________ > Users mailing list > Users@ovirt.org > http://lists.ovirt.org/mailman/listinfo/users > _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
