what are the steps to swap/upgrade/reboot my main storage domain with minimum downtime
I need to upgrade my main domain storage (NFS) which hosts 100s of VMs and templates including the hosted engine. Can I put the data center in global maintenance, do a quick sync and swap of the domain storage and bring it back up without missing a beat?
Depends what you mean by "sync" and "swap". If you can keep the same NFS endpoint, but swap-in your upgraded storage under the hood then I think you can do as you propose. Stop all VMs, put the storage domain in maintenance, make you changes and bring the domain out of maintenance. However, if you're moving to a different NFS server, or even different path on the same server then I think the answer is no. In this scenario you'd need to create a new domain and move each vdisk across. ---- On Wed, 09 Feb 2022 06:07:44 +0000 Pascal D <pascal@butterflyit.com> wrote ---- I need to upgrade my main domain storage (NFS) which hosts 100s of VMs and templates including the hosted engine.

I am wondering if having the engine hosted on ovirt is actually a good idea. It seems to me that it complicates things when doing some major upgrades like with swapping domain server and such. Does that make sense? Should I keep the engine separate on another hypervisor maybe? On Wed, Feb 9, 2022 at 3:14 AM Alan G <alan+ovirt@griff.me.uk> wrote:

Sorry, I missed the fact that you also have HE in the same domain. I think the previous statement still stands. But you'd be advised to stop the ovirt-ha-agent and ovirt-ha-broker on all hosts as well. ---- On Wed, 09 Feb 2022 06:07:44 +0000 Pascal D <pascal@butterflyit.com> wrote ---- I need to upgrade my main domain storage (NFS) which hosts 100s of VMs and templates including the hosted engine.
