  Hello.

I'm trying to implement following backup scenario for my VMs:

storage domain is a volume on netapp appliance connected to oVirt cluster

via NFS3. Netapp produces its zero copy snapshots of this volume.

I want to be able to restore VMs from these snapshots, e.g.

Netapp can export snapshot to ovirt as another NFS volume after that

I want to be able to import VM or attach VM disks from snapshot volume

to VM and start it. As far as I understand it is basic backup|migration scenario

when user wants to move VMs from one ovirt DC to another ovirt DC.

Right now I cannot import snapshot volume which contains exactly same domain

metadata (in dom_dm/ directory) as original volume (which I cannot detach since

it hosts disks for running VMs). I tried to rename dom_md/, but with no success in

domain import process.

Maybe someone in this list uses same scenario for VM backup and can give some advice.

Hi Zinovik,

Have you tried using the scan disks procedure[*] (which scans the domain for unregistered floating disks)?

You can find it under 'Storage -> Domains -> Disks -> "Scan Disks" button (in the Kebab Menu)'.

[*] https://www.ovirt.org/develop/release-management/features/storage/importstoragedomain/#work-flow-for-scanning-unregistered-floating-disks---ui-flow

I cannot even attach snapshot volume.

Disks scanning is available only for attached storage domains.
