Hello community, We use a NFS export domain for full backups. Sometimes I have to restart the NFS file server, but when I just restart that server, without doing anything in oVirt (I guess normally I should put the domain in maintenance mode), it can happen that hosts and VMs a crashing. I had one time even the issue, that after a crash one XFS file system on one host got damage and I had to fix that. My though was now, because I make only one time a week a VM full backup, I only mount the export domain in this time. Is there an easy way to do this, with the API? Or would you have a other hint, how to solve this issue? Have a good day! Jonathan
You can mount the NFS outside oVirt and backup to it Also, you can use pacemaker (if the NFS is a linux server) to ensure that failover is immediate and with NFS v3 the recovery of the clients should be fast enough to avoid troubles.

Thanks, Strahil! Am 23.06.21 um 17:33 schrieb Strahil Nikolov:

But this is only possible with OVA export, right? And not the traditional way with making a snapshot and export the VM to the export domain.

I think that you can use the API to do backup to the "local" NFS. Most probably you can still snapshot and copy the disks , but this will require a lot of effort to identify the read only disks and copy them.

A while ago I wrote an ansible playbook to backup ovirt vms via ova export to storage attached to one of the hosts (nfs in my case). You can check it out here: https://github.com/silverorange/ovirt_ansible_backup I’ve been using this for a while and it has been working well for me on ovirt 4.3 and 4.4 On Thu, Jun 24, 2021 at 4:52 PM Strahil Nikolov via Users <users@ovirt.org> wrote:
