I was wondering about gluster g-rep, but what if something that just happened to me (gluster f*ckup) will get replicated too. At this point (lost 3 HCI clusters due to Gluster) I am not really trusting this piece of software with my live data *and* my backups. I am really protecting myself against Gluster than anything else. So for backup purposes: The less Gluster, the better. -Chris.

It is also possible to export VMs as OVA which can then be reimported back into oVirt. I actually just wrote an ansible playbook to do this very thing and intend to share my finding and playbooks with the ovirt community hopefully this week. > On Thu, Feb 6, 2020 at 12:18 PM Christian Reiss <email(a)christian-reiss.de <mailto:email@christian-reiss.de>> wrote: > Hey folks, > Running a 3-way HCI (again (sigh)) on gluster.
