Hello everybody,
I have a question, or more precisely information or best practice.
I use oVirt 3.1 with an attachment on fiber channel on my SAN. Makes it even the San snapshots that are replicated on a remote site.
it's a procedure for adding a new "Storage" Domain to another Data Centers (oVirt) in order to recover the state of a VM snapshoted by the SAN?
If I understand correctly, the remote SAN of you can snapshot the storage domain(physical lun in the SAN) lively. And you hope to recover the storage domain with the previous snapshot stored in the SAN. So you create a new "storage" domain for another data center and restart the VM from the newstorage domain. I am not sure if the VM disks in the storage domain snapshot is in consistent date if the SAN snapshot the VM in a running state. I think the VM OS should be notified and make sure it is in consistent state before the SAN can do the snapshot, also the VM OS should be notified with the finish of the snapshotting..
I've read the documentation on Disaster Recovery but it's for the site-to-site failover (i don't have dual architecture of ovirt) while my demand here is for the state recovered a current domain. And only to export the VM(snapshoted by a san) for restore in the current storage (production).
thank you Pierre _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
