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?


In the original RHEV instance - there were 3 storage domain
i) Hosted engine storage domain: engine
ii) Master data domain: vmstore
iii) An export domain: expVol (no data here)

To my backup RHEV server, I only imported vmstore.

Just to be sure, can you look into the server which the engine storage domain 
resides on.
Is there a chance that 6f4da17a-05a2-4d77-8091-d2fca3bbea1c could be there?

Also do you have an old engine log, is there a chance to look for image 
6f4da17a-05a2-4d77-8091-d2fca3bbea1c in there, to see when it was created and 
if there were any problems in the process.



I checked the engine logs and it seems that image 
6f4da17a-05a2-4d77-8091-d2fca3bbea1c was removed as part of snapshot merge. 
Could it be that the OVF was not updated?


The OVF_STORE is being update every 60 minutes or when a Storage
Domain is moved to maintenance.
If the DR process was done before the OVF_STORE got updated and the
setup was destroyed then that might be the reason for the missing
image in the OVF.

The problem is that this image id is already part of the images chain
configured in the VM's OVF.
As a work around maybe you can create a new volume with VdsClient
createVolume on the Host with the same UUID.
or maybe to merge all the disk's snapshots through the vdsClient and
once there will be only one volume you can register this disk as
floating disk.

Is there a way via API to update OVF_STORE?
This way before the DR process we can ensure that the OVF_STORE is referring to the correct images.

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)?


No - there was no file with this id (checked both in the original RHEV instance)
[root@dhcp42-105 mnt]# pwd
/rhev/data-center/mnt
[root@dhcp42-105 mnt]# find . -name  6f4da17a-05a2-4d77-8091-d2fca3bbea1c
[root@dhcp42-105 mnt]#


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?


No. The only operation done was creation of a snapshot - and it completed 
before the recovery was attempted.

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.

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?
