Ok. I will do some tests reducing OvfUpdateIntervalInMinutes and
check if OVF_STORE is updated when a new snapshot is created.<br>
Thanks.<br>

<pre wrap="">You don't have to detach the Storage Domain to refresh the OVF_STORE, but instead move it to only to maintenance.
You can also change the interval value OvfUpdateIntervalInMinutes in the vdc_options table which is by default executes every 60 minutes and sync the OVF_STORE disk with the VMs' and Templates' data.

Hi,
I noticed that OVF_STORE volumes are not generated periodically as expected
[1].
It seems like the OVF_STORE volumes are only generated when the Storage
Domain is detached from Engine, which is not feasible if we want to keep the
VMs running.
1) Is there any way to force the OVF_STORE volume creation without detaching
the Storage Domain?
This would be very usefull for disaster recovery, since Storage Domains can
be backed up and VM can be reimported.
But if the OVF_STORE volumes are not updated, critical information like the
ID of the VM active snapshot will get lost.
If the VM is restored with a previous snapshot (not the last one), all
information written after the last snapshot known by the OVF_STORE will get
lost.
2) On the other hand, the only way I know to re-read the OVF_STORE content
with the VM information contained in a Storage Domain, is by detaching and
re-attaching it.
I wonder if there is also any way to re-read the OVF_STORE?
[1] : This can be verified very easily by changing a running VM properties
(change its name or create a snapshot), copying the whole storage domain and
importing it into another Engine (POOL_UID and CHECKSUM must be removed from
metadata in order to be able to attach to another Datacenter).
PS: I'm on 3.6 RC. 1.
