Hello Didi and all,
Thank you for that documentation... I actually looked at something similar (
https://www.ovirt.org/develop/release-management/features/storage/imports...
) before writing. Regarding the Section 3.1 "Disaster Recovery Guide --
Active-Passive" method... I need to understand what this means, "Storage
domains that contain virtual machine disks and templates in the primary site must be
replicated". What does the document mean by "replicated"? To use the
document terminology, we have a Site A (SAN LUN A) and Site B (SAN LUN B) which is
asynchronously (3 hour) replication of the VMs, and if Site A goes away, we can present
LUN B to Site B oVirt cluster KVM host. After presentation, I assumed I would have to
create a new Storage Domain and affix the LUN B to it. However the documentation says
"site must be replicated", so what exactly does that mean, compared to what we
are doing/thinking? Another thing I noticed in looking into this is an Imported Domain
(from an Exp
ort Domain) presents a "VM Import" TAB in the Storage Domain details, while a
regular Storage Domain setup does not appear to offer that -- unless this is a conditional
thing? (And of course when Site A goes down I cannot perform a detach of an exported
storage domain.) If I create the Site B oVirt cluster new Storage Domain for the LUN B,
will that present a "VM Import" function tab? (In order to grab the VM info
from the LUN B and import it into the cluster.) I'm also looking to avoid needing to
delve into the Ansible scripts, if the needed functionality for recovery can be done in
oVirt/KVM.
Many thanks again.
