Description Germano Veit Michel 2018-01-19 03:20:56 UTC 
+++ This bug was initially created as a clone of Bug #1469143 +++

Description of problem:
I see that when ever an upgrade of RHV-H 4.1.2 to 4.1.3 is done Hosted Engine Ha state is in Local Maintenance.

Version-Release number of selected component (if applicable):
ovirt-host-deploy-1.6.6-1.el7ev.noarch

How reproducible:
Always

Steps to Reproduce:
1. Install HC setup with RHV-H 4.1.2 async build
2. Now add all the required repos
3. There is an upgrade symbol next to the hypervisor.
4. click on that.


Actual results:
 RHV-H host gets upgraded to 4.1.3 leaving the Hosted Engine HA state in 'Local Maintenance"

Expected results:
 RHV-H host gets upgraded to 4.1.3 leaving the Hosted Engine HA state should not be in 'Local Maintenance"

Additional info:

Adding hosted-engine --vm-status before and after upgrade:

--- Additional comment from Yaniv Lavi on 2017-07-17 05:19:22 EDT ---

Can you check for a regression in the hot activation flow? It is supposed to move the host out of local maintenance.

--- Additional comment from Artyom on 2017-07-19 07:48:04 EDT ---

So it does not a regression in the host activation flow, the problem is:
1) Move host to maintenance via engine(will activate HE "LocalMaintenance" state)
2) Upgrade the host via the engine, after the upgrade host moved straight forward to up state, so from the engine side host is UP, but from the HE side, the host has state "LocalMaintenance", because no one ran activate command on the engine side.

--- Additional comment from Sandro Bonazzola on 2017-11-18 02:50:36 EST ---

Denis is this going to land in 4.2.0? If not please re-target.
Comment 2 Marina Kalinin 2018-01-30 20:49:58 UTC 
Germano, sounds like my bz#1489982.
Comment 3 Germano Veit Michel 2018-01-30 22:37:47 UTC 
(In reply to Marina from comment #2)
> Germano, sounds like my bz#1489982.

Indeed.

So your BZ was a dup of Bug #1469143, which wasn't closed when it was fixed. Then  I cloned the original BZ downstream.

Also your BZ says this was fixed in 4.2, but the original BZ is targetted to 4.3
And I reproduced this 4.1.8.

Can it get any more confusing? ;)
Should we close them all or we want to get this fixed in 4.1.10? I think it should be fixed in 4.1.10 too as after a round of upgrades all HE hosts might be in maintenance mode, defeating HA, so it's quite serious. What do you think?
Comment 5 Yaniv Lavi 2018-02-14 12:50:41 UTC 
This is severe and should not be targeted so far in the future.
The maintenance mode for HE should be lock the the engine maintenance mode, if the engine is up.

Maintaining this in upgrade it elementary. Retargeting.
Comment 6 Martin Sivák 2018-02-14 13:53:35 UTC 
Nikolai, we need to figure out if this is still broken and where. Can you please try reproducing it with 4.1.8 -> 4.1.9 upgrade? It might be RHEV-H specific too.

Its HC specific issue.
Kasturi Narra, please provide your input.
Comment 8 Nikolai Sednev 2018-02-14 14:01:27 UTC 
Jiri, have you seen such an issue during your latest upgrade set of tests?
Comment 9 Marina Kalinin 2018-02-14 14:51:39 UTC 
Hey, why is it HC specific?
I believe what happens here is when the host is out of engine side maintenance due to upgrade or reinstall, it should also cancel the HE local maintenance, that's all. Today it enables local HE maintenance once we put the host in maintenance in RHV UI, through engine, but it never cancel's the HE maintenace when it is auto-activated back on the engine side. And this is the problem.

So there is a confirmation from your side that this is not HC specific.Regular RHEL/RHVH ha-hosts will be hitting the same issue during the upgrade.
Martin, please review Comment #9.
Comment 11 Martin Sivák 2018-02-15 09:47:10 UTC 
Nikolai, we asked for a test of this to see if it really is happening and where. There are conflicting information with regards to RHEV-H and branches (4.1 vs 4.2).

Since all we have now are opinions, I would like someone from QE to provide some hard data, before we decide what do to with all the linked bugs.

I wonder if this could be closed as DUP of #1489982
Comment 21 Martin Sivák 2018-02-26 12:20:36 UTC 
Can you please check what the states are when you upgrade a RHEV-H host?

1) You put the host to maintenance using webadmin button
2) You update the node
3) The node reboots
4) Does it stay in maintenance mode (in engine) or does it move to Up automatically?

It stays in maintenance state.
