I have 3 nodes running node ng 4.3.9 with a gluster/hci cluster. How do I upgrade to 4.4? Is there a guide?

My confusion is that those documents do not describe any gluster related tasks for Ovirt Nodes. When I take a node down and install Ovirt Node 4.4 on it, won't all the gluster bricks on that node be lost? The part describing "preserving local storage", that isn't anything about Gluster, correct? *Vincent Royer* *778-825-1057* <http://www.epicenergy.ca/> *SUSTAINABLE MOBILE ENERGY SOLUTIONS* On Tue, Sep 22, 2020 at 8:31 PM Ritesh Chikatwar <rchikatw@redhat.com> wrote:

Before you reinstall the node , you should use 'gluster volume remove-brick <VOL> replica <old number - 1> ovirt_node:/path-to-brick' to reduce the volume to replica 2 (for example). Then you need to 'gluster peer detach ovirt_node' in order to fully cleanup the gluster TSP. You will have to remove the bricks that are on that < ovirt_node > before detaching it. Once you reinstall with EL 8, you can 'gluster peer probe <reinstalled_ovirt_node>' and then 'gluster volume add-brick <VOL> replica <current count + 1> reinstalled_ovirt_node:/path-to-brick. Note that reusing bricks is not very easy, so just wipe the data via 'mkfs.xfs -i size=512 /dev/block/device'. Once all volumes are again a replica 3 , just wait for the healing to go over and you can proceed with the oVirt part.

Not to give you any false hope, but when I recently reinstalled my oVirt 4.4.2 cluster, I left the gluster disks alone and only reformatted the OS disks. Much to my surprise, after running the oVirt HCI wizard on this new installation (using the exact same gluster settings as before), the original contents of my gluster-based data domain were still intact. I certainly wouldn't count on this behavior with any important data, though. --Mike On 9/23/20 1:40 PM, Vincent Royer wrote:

I am hoping for a miracle like that, too. In the mean-time I am trying to make sure that all variants of exports and imports from *.ova to re-attachable NFS domains work properly, in case I have to start from scratch. HCI upgrades don't get the special love you'd expect after RHV's proud announcement that they are now ready to take on Nutanix and vSAN.
Interested to hear how upgrading 4.3 HCI to 4.4 goes. I've been considering it in my environment but was thinking about moving all VMs off to NFS storage then rebuilding oVirt on 4.4 and importing. On Thu, Sep 24, 2020 at 1:45 PM <thomas@hoberg.net> wrote:

It's a bit disheartening that HCI users don't have an easier upgrade path. So far there's a lot of 'this might work' or' that might work', and good luck. Certainly doesn't inspire much confidence. Every time there is a survey asking what the pain points are, I say "updates!!", but they seem to be getting more and more complicated.

Have you checked the oVirt 2020 conference videos ? There was a slot exactly on this topic- I think ansible was used for automatic upgrade. I prefer the manual approach , as I have full control over the environment.

I was looking forward to that presentation for exactly that reason: But it completely bypassed the HCI scenario, was very light on details and of course assumed that everything would just work, because there is no easy fail-back and you're probably better off taking down the complete farm during the upgrade. If you are actually depending on that farm to operate,... In the mean-time I try to make sure I have a plan-B and C solution in case the official procedure fails, but have *.ova (plan-C) imports fail (again) in extract_ova.py on the single-node 4.4.2 HCI cluster that I have set up as target to do migration testing... a bug far to familiar for a newest release. I'll be testing re-attachable NFS domains next (plan-B), but for me *.ova exports and imports are still the most fundmental operations any hypervisor needs to support: If OVA is the wrong file format, fine, just do another one. But IMHO turning a machine into a file and a file into a machine is the very definition of what hypervisors do. And a release that doesn't seem to test this operation, does not rhyme with "solution for your entire enterprise" on the oVirt home page.
