Hi,
Is it possible to have a shared Storage domain between 2 Datacenter in
oVirt?
We do replicate a FC Volume between 2 datacenter using FC SAN storage
technology and we have an oVirt cluster on each site defined in separate
DCs. The idea behind this is to setup a DR site and also balance the
load between each site.
What happens if I do import a storage domain already active in one DC,
will it break the Storage domain?
Thanks for any information..
Regards,
Arsène

Hi
I have in production the scenery something similar to what you've described=
.
The "enabling factor" is represented by an "storage virtualization"
set of =
appliances, that maintain mirrored logical volume over fc physical volumes =
across two distinct datacenters, while giving rw simultaneus access to clus=
ter hypervisors split between datacenters, that run the VMs.
So: cluster also is spread across dc, no need to import nothing.

Hi Roberto,
Thanks for your information but....
When I'm writing about DC I mean defined DC in oVirt and so far I could
see that when you define a storage domain in one oVirt DC it will not be
available in another DC and I don't know what would happen if I would
import it on the second DC.
In your setup, did you just define 1 DC and multiple clusters?
Regards,
Arsène

Hi Arsène,
The only storage domain that can be shared between datacenters is the iso
domain
But that's not what you're looking for. You can't share a data domain
between two datacenters.
As for importing a storage domain which is active on one datacenter to
another datacenter, there are two cases:
- If the datacenters are in the same oVirt setup, that won't be possible,
and the operation will not be performed.
- If the datacenters are in two different oVirt setups, the import to the
second datacenter will succeed, but you will experience issues in the first
datacenter.
The reason for that is that the host in the second datacenter overrides the
storage domain metadata when importing it.
Therefore, you cannot import a storage domain to a second datacenter while
it is active on the first one, anyway.
Regards,
Idan

Hi Idan,
Thanks a lot for your answer, that's clear now.
I will change my setup and use 2 cluster in the same DC instead.
In the case using 2 cluster in the same DC I've noticed that all Storage
domain have to be available for all clusters, in my case I use SAN
Storage. Is this by design or is there a way to have some Storage Domain
only available on one cluster but not on the others?

Hi Arsène,
There's no way to have a storage domain that is available in one cluster
but not available in the other, in the same dc. It is by design.

Hi Idan,
Thanks a lot for your answer, that's clear now.
I will change my setup and use 2 cluster in the same DC instead.
In the case using 2 cluster in the same DC I've noticed that all Storage
domain have to be available for all clusters, in my case I use SAN Storage.
Is this by design or is there a way to have some Storage Domain only
available on one cluster but not on the others?
Regards,
Arsène

Hi Arsène,
The only storage domain that can be shared between datacenters is the iso
domain
But that's not what you're looking for. You can't share a data domain
between two datacenters.
As for importing a storage domain which is active on one datacenter to
another datacenter, there are two cases:
- If the datacenters are in the same oVirt setup, that won't be possible,
and the operation will not be performed.
- If the datacenters are in two different oVirt setups, the import to the
second datacenter will succeed, but you will experience issues in the first
datacenter.
The reason for that is that the host in the second datacenter overrides
the storage domain metadata when importing it.
Therefore, you cannot import a storage domain to a second datacenter while
it is active on the first one, anyway.
Regards,
Idan
