Hi Strahil,
We got to meet at next oVirt conf, as all beer rounds will be on me!
Ok, just to be sure, so upon those 8 hours:
* Node1 #ssh root@ovirt-engine “shutdown -h now” <= engine is currently running,
via virsh start, on this Node1
* Node1 # virsh undefine HostedEngine
* Node2 # hosted-engine –vm-start <= Node3 still needs to be updated
* Node2 # hosted-engine --set-maintenance --mode=none
* Node3 # hosted-engine --set-maintenance --mode=local
* Patch Node3
* Test HA

Dear Strahil,
Thank you for all knowledge sharing and support so far.
The procedure went fine so far and I have the Engine running on
Node1
(it was on Node3).
However, I see “strange things” :
* Engine is running and I have access to WebUI as well - good.
* None of the HA Nodes actually show who is hosting the Engine atm
–
all crowns are gray - Strange
* If I look at the list of VMs, I see HostedEngine VM as powered
off
- Strange
Can I safely assume procedure went fine and now the Engine conf sync
time of 12 hours started or something went wrong?
Kindly awaiting your reply.

Hi Marko,
If the other VMs work without issues -> it's worth
trying.

Strahil Nikolov
Hi Marco,
As the VM was started manually (and not by the ovirt-ha-agent) - this is expected.
Keep the engine running and it will update it's own OVF . On the safe side - 8
hours is an overkill, but will save you from repeating the procedure.
Last step is to shutdown the VM from inside, undefine it 'virsh undefine
HostedEngine' and last start it manually via vdsm 'hosted-engine --vm-start'
on one of the updated nodes.
Once you do a migration from one updated to another updated node, you can remove the
global maintenance.
'hosted-engine --set-maintenance --mode=none'
Next , you can test the HA of the engine by powering it off:
A)ssh to not-yet-updated node and set it in local maintenance:
hosted-engine --set-maintenance --mode=local
B) ssh engine "poweroff"
Check if the engine is powered up on the last of the 3 nodes (also updated).
Don't forget to patch the last node (and remove the maintenance after the
reboot).
The hard part is over - now you just need to verify that the HA is working properly.
Best Regards,
Strahil Nikolov
