Strahil, yes this is similar to the approach I have used to upgrade my hci cluster. This thread is in regards to the ui cluster upgrade procedure. It fails to update after the first host is rebooted because the gluster volume is still in a healing state and the attempt to set the second host to maintenance fails because quorum is not met.

I keep reading this chain and I still don't get what/who should wait for the cluster to heal...
Is there some kind of built-in autopatching feature?

Here is my approach:
1. Set global maintenance
2. Power off the engine
3. Create a  gluster snapshot of the engine's volume
4. Power on engine manually
5. Check engine status
6. Upgrade engine
7. Upgrade engine's OS
8. Reboot engine and check health
9. Remove global maintenance
10. Set a host into local maintenance (evacuate all VMs)
11. Use UI to patch the host (enable autoreboot)
12. When host is up - login and check gluster volumes' heal status
13. Remove maintenance for the host and repeate for the rest of the cluster.

I realize that for large clusters this approach is tedious and an automatic approach can be scripted.

Hi Jayme,
It would be great if you could raise a bug regarding the same.

This sounds similar to the issue I hit with the cluster upgrade process in my environment. I have large 2tb ssds and most of my vms are several hundred Gbs in size. The heal process after host reboot can take 5-10 minutes to complete. I may be able to address this with better gluster tuning. 

Either way the upgrade process should be aware of the heal status and wait for it to complete before attempting to move on to the next host.

I’m aware of the heal process but it’s unclear to me if the update continues to run while the volumes are healing and resumes when they are done. There doesn’t seem to be any indication in the ui (unless I’m mistaken)
