I'd say very good luck, concentration and coffee...

If you got a backup of /etc/glusterd and /var/lib/glusterd you should be able to restart gluster on that node (so no syncing will be needed). Keep in mind that I haven't migrated yet, so I can't guarantee it will work ;) Best Regards,Strahil Nikolov On Thu, Mar 25, 2021 at 20:39, Jayme wrote: ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/3MCVU3COMB3SDXJIHL3L5DOO434DWPEE/ ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/SHHBBF7FAHG6Q73PLXB5MSFWXXEEIGIQ/

After setting one host to maintenance to reinstall with EL8 is anything else required such as reducing gluster?

Yes you can upgrade without a 4th host. Actually, first update to latest 4.3.10 or your backup won't be valid for update to 4.4 You will need to set one of the hosts into maintenance and then reinstall that host with EL8 (CentOS or another).Once you install that node, you need to readd it to the Gluster Cluster and then deploy from backup the new engine (use new gluster volume) using that EL8 host. Once it's successful, the rest of the hosts should be available and you will be able to remove one of the other nodes, reduce gluster, reinstall , get gluster running and add the host again in oVirt.

I'm using GlusterFS storage for the self hosted engine and for some VMs. I also have some other VMs running from an external NFS storage domain. Is it possible for me to upgrade this environment to 4.4 while keeping some of the VMs on GlusterFS storage domains running? Does the upgrade require an additional physical host? I'm reading through the upgrade guide and it's not very clear to me how the engine is reinstalled on CentOS8. Do you need a 4th host, or do you take one of the three existing hosts down, wipe it and install ovirt node 4.4? Would it be easier for me to just move all VMs to my NFS storage domain, wipe all hosts and deploy a brand new 4.4 HCI cluster then import the NFS storage domain? Will the 4.3 VMs on the NFS storage domain import/run properly into the new 4.4 deployment or are there any other considerations? ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/62ZSJ5IMZ43HCM356DJH6D3M76F3TGJF/ ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/MQVWUXSRPFGAELZ6EIPQFPOG2P5CJYWU/
