Hi Coffee,


The OVF_STORE disk sync the VMs and Templates data in an un-synchronous way every 60 minutes (see [1])
this might be the reason that sometime you see the entities candidate for import and sometime you don't.

There are patches which sync the VMs/Templates data once the Storage Domain is being moved to maintenance
the bug is https://bugzilla.redhat.com/1138124
the patch for fixing it is at http://gerrit.ovirt.org/#/c/33158/

The REST examples can be found here:
http://www.ovirt.org/Features/ImportStorageDomain#REST

To see the candidates for import you should use the following URL:
http://localhost:8080/api/storagedomains/68ca2f73-9b15-4839-83c9-859244ad2cd3/vms;unregistered

You should see also the links for unregistered Vms and Templates,
I will take a look at it now and let you know if this was fixed already.


[1]
At http://www.ovirt.org/Features/ImportStorageDomain#Restrictions:
"For better sync of the entities in the Storage Domain with the OVF_STORE disk, it is better to update the OvfUpdateIntervalInMinutes option in vdc_options from 60 minutes to 2-5 minutes, as so : update vdc_options set option_value = 2 where option_name = 'OvfUpdateIntervalInMinutes'; (see [5])"


Regards,
Maor

> I have two setups: DC-A, DC-B, NFS storage: test-import
>
> My steps are:
> 1. In DC-A, create some VMs and create their disks on test-import
> 2. maintenance the storage test-import, detach the storage from DC-A
> 3. login to DC-B, click "import domain", chose Data/NFS and enter the path of
> test-import, click "ok"
> 4. Active storage test-import
>
> Expect result:
> 1. there are two new subtags in test-import: "vm import" and "template
> import"
> 2. the VMs which were create on test-import are listing in the subtag "vm
> import"
> 3. I can chose VM and import it to DC-B

> However, it worked randomly:
> sometimes i can see subtags with VMs in DC-B, but sometimes i can not see any
> VM, and sometimes i can't even see the subtags.
