Hello,
failing to find a procedure how to actually upgrade a HA cluster, I did
the following witch turned out to be working pretty well.
I am somewhat new to oVirt and was amazed how well actually; I did not
need to shutdown a single VM (well, one because of mem usage; many of my
running VMs have fancy stuff like iscsi and FC luns via a Quantum
Stornext HA Cluster):
1. Set cluster to global maintance
2. Login to ovit engine and to the upgrade according to the release
nodes.
3. After the upgrade is finished and the engine running, set the
first Node in local maintenance.
4. Login the first node and yum update (with the removal of
ovirt-release as mentioned in release notes).* I rebooted the
node because of the kernel update.
5. Return to oVirt and reinstall the Node from GUI, it will be set
to operational automatically**
6. Repeat steps 3-6 for the rest of the Nodes.
7. Remove global maintenance.
8. Update the last Node.***
* I first tried to do this with re-install from GUI. This failed; so I
used the yum - update method to update all relevant services
** I do not know if this was necessary. I did this because the
hosted-engine --deploy does the same thing when adding a host.
*** I found this to be necessary because I had all my Nodes in local
maintenance and could not migrate the Hosted engine from the last node
any more. The host activation in oVirt did not remove the local
maintenance set prior to the update (witch it should, IMHO). It might be
desirable to have a hosted-engine command option to remove local
maintenance for that reason.

Hi Martin,
Thanks for sharing!
A few notes on your nice 8 steps ;)
- There are 2 maintenance modes to cover host maintenance (local) and
VM maintenance (global). Global maintenance disarms all HA hosts in
the cluster, so use it with caution as there's no fail over in this
mode.
- Initially these were available only as a command line[1]. Since 3.4.0,
this was integrated into the UI, so all you need to do is move a host
to maintenance in order to achieve local maintenance, and activate it
to remove the maintenance mode. For global maintenance, right click
the engine VM, and you will see enable/disable ha-maintenance for
the global mode.
- No need to re-install nodes. All you need to do is activate it.
- Basically a standard procedure should include:
* Move host to maintenance, login and update the host, activate the host.
* Follow the above for all other HA hosts
* Set the engine VM to ha maintenance (global), login to the vm and
upgrade it, unset vm's ha-maintenance.
Appreciate your feedback.
Also, were you aware of [1] or did you look for info elsewhere? I'd like
to know what we can do to improve documentation.
Thanks again,
Doron

One thing that’s still unclear to me in this this setup is what’s needed to ensure all the
nodes or get updates? Just do yum updates? I’ve have mixed success with the “reinstall or
update” link in the GUI, seemed like it worked properly when I updated to 3.4.0, but
trying to do the 3.4.1 update it failed for no apparent reason and I wound up doing yum
updates on the host nodes…

One thing that’s still unclear to me in this this setup is what’s needed to
ensure all the nodes or get updates? Just do yum updates? I’ve have mixed
success with the “reinstall or update” link in the GUI, seemed like it
worked properly when I updated to 3.4.0, but trying to do the 3.4.1 update
it failed for no apparent reason and I wound up doing yum updates on the
host nodes…

Hi Darrel,
the flow you described should work, and if not there's possibly a bug
in the host deployment. We need more details from your log files
to better understand what happened. For example, did you have your
repositories set correctly? Did you notice an error in the events pane?
The above scenario is generic regardless to manual or UI-based updates.

Hi
Doron,
thanks for pointing out [1]. I was not aware of this, basically these
are the steps I wrote ;)=20
Thanks for pointing out the availability of the maintenance mode in the
GUI; I noticed local maint. being transparent (from GUI -> command line,
though not the other way around).
Also, I need the global maintenance for step one because of the engine
upgrade because I suspect ha-agent would interfere because of necessary
service restarts/downtime.
It could have been reactivated much earlier though!
Cheers,
Daniel
