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 is 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.
6:48 a.m.
This is what we discussed on BZ#1268842, right?

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.

Maor

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