> Our PHX environment was updated from 3.5 with host reinstalls which left behind a stale host:
> ID host
> 1 ovirt-srv01 (stale)
> 2 ovirt-srv02
> 3 ovirt-srv03
> 4 ovirt-srv01
> Since [BZ#1215437|https://bugzilla.redhat.com/show_bug.cgi?id=1215437] and [BZ#1321889|https://bugzilla.redhat.com/show_bug.cgi?id=1321889] were included in 3.6 it is now possible to fix the stale ID for ovirt-srv01 since it's pending 4.1 upgrades anyway
> Action plan:
> 1) put ovirt-srv01 in Maintenance
> 2) remove from Engine
> 3) re-deploy (or just clean HA agent cache?)
> 4) run hosted-engine --deploy and re-add with ID=1
> 5) put in Maintenance again, stop HA agent
> # service ovirt-ha-agent stop
> 6) clean up leftover ID=4:
> # hosted-engine --clean-metadata --host-id=4
> 7) start agent, wait for FSM to initialize, activate host
> # service ovirt-ha-agent start
> Will test it on my test upgraded environment first.
