Okay I've finally found some time to fix my problems with the old
storage domains.
I reinstalled the box and it's running fine but I'd love to recover the
old domain I used for downloading stuff.
I just reread your email from march 16th and I'm going to try the thing
you've suggested, so I hope you're still willing to help me :).
Option A -
*doesn't require copying the disks
*if your vms had snapshots involving disks - it won't work currently.
let's try to restore a specific vm and continue from there - i'm adding here info
- if needed i'll test it on my own deployment.
A. first of all, let's get the disks attached to some vm : some options to do that.
*under the webadmin ui, select a vm listed under the "export" domain, there
should be a disks tab indicating what disks are attached to the vm - check if you can see
the disk id's there.
B. query the storage domain content using rest-api - afaik we don't return that info
from there. so let's skip that option.
1. under the storage domain storage directory (storage) enter the /vms directory - you
should see bunch of OVF files there - that's a file containing a vm configuration.
2. open one specific ovf file - that's the vm that we'll attempt to restore - the
ovf file is a file containing the vm configuration
*within the ovf file look for the following string: "diskId" and copy those ids
aside, these should be the vm attached disks.
*copy the vm disk from the other storage domain, edit the metadata accordingly to have
the proper storage domain id listed
*try to import the disks using the method specified here:
https://bugzilla.redhat.com/show_bug.cgi?id=886133
*after this, you should see the disks as "floating", then you can add the vm
using the OVF file we discussed in stage 2 using the method specified here:
http://gerrit.ovirt.org/#/c/15894/
In order to get the disks attached to a VM, I
need to move them into a
new import domain. How should I determine which files to get?
There were multiple VMs in the directory, each having multiple
LVM-based storage domains so I just had a look, I 'm only interested in
images from "Downloadbak".
I found:
engine=# select
image_guid,size,parentid,imagestatus,volume_type,volume_format,active
from images order by parentid;
image_guid | size |
parentid | imagestatus | volume_type | volume_format | active

What's the best way of getting those attached to another VM? Moving them
into an import repo?
Cheers,
Boudewijn
