Hi Sahina,

The disks with snapshots should be part of the VMs, once you will register those VMs you should see those disks in the disks sub tab.

Maor,

I was unable to import VM which prompted question - I assumed we had to register disks first. So maybe I need to troubleshoot why I could not import VMs from the domain first.
It fails with an error "Image does not exist". Where does it look for volume IDs to pass to GetImageInfoVDSCommand - the OVF disk?

Usually the "image does not exists" message is prompted once the VM's disk is managed in a different storage domain which were not imported yet.

Few questions:

1. Were there any other Storage Domain which are not present in the setup?

2. Can you look for the image id 6f4da17a-05a2-4d77-8091-d2fca3bbea1c in your storage server (Search on all the rest of the storage domains)?

Were there any operations being done on the VM before the recovery such as remove disk, move disk, or a new creation of a disk?

Maor

Regarding floating disks (without snapshots), you can register them through REST.

If you are working on the master branch there should be a sub tab dedicated for those also.

Regards,

Maor

Hi all,

I have a gluster volume used as data storage domain which is replicated to a slave gluster volume (say, slavevol) using gluster's geo-replication feature.

Now, in a new oVirt instance, I use the import storage domain to import the slave gluster volume. The "VM Import" tab correctly lists the VMs that were present in my original gluster volume. However the "Disks" tab is empty.

GET https://new-ovitt/api/storagedomains/5e1a37cf-933d-424c-8e3d-eb9e40b690a7/disks;unregistered -->
<disks/>

In the code GetUnregisteredDiskQuery - if volumesList.size() != 1 - the image is skipped with a comment that we can't deal with snapshots.

How do I recover the disks/images in this case?

Further info:
