Hi Gianluca,
Thank you for reply,
I found VMSTORE volume mount options across all six nodes but found only 3 primary nodes in “Hosted_engine” volume, files are attached.
Volume is “Distributed Replicated” across all 6 nodes, 2 x 3 = 6.
I have edited file “/etc/ovirt-hosted-engine/hosted-engine.conf” to change Mount options for the Hosted Engine Volume, but did not get success, will check after putting cluster in maintenance mode and try.
Will follow
https://lists.ovirt.org/archives/list/users@ovirt.org/thread/3NCQ5F7QDNSBQAJV7OEABKZTBI62KADM/
Suggest any other solution if any.
Thanks in advance.

Hi,
i have a Six node Stretched HCI cluster with 2 x 3 =6 distributed Replicated bricks, want to achieve Active - Active Disaster Recovery , if my three hosts in DC power Down or Failed my DR Site Three node should take care of running virtual machines.
During Split-brain scenario Ovirt-Hosted-Engine VM goes in PAUSE mode and not restarting on DR hosts and waited for long time, due to this my all production VMs are not restarting on DR Site.
Hi,
even if the guide mentions GlusterFS as supported storage domain for Active-Active DR scenario and Self Hosted Engine configuration as a supported one for Active-Active DR scenario, and it doesn't explicitly mention that HCI configurations
are not supported, I have always interpreted that the storage replication mentioned inside the docs refers to "external" replication, provided by the storage array hw architecture, not by RHV HCI sw solution itself. In that sense your architecture should not
be a supported one for Active-Active DR scenario.
Some wordings inside the docs:
"
...
This configuration requires replicated storage that is writeable on both sites...
...
The sites require synchronously replicated storage that is writeable on both sites with shared layer 2 (L2) network connectivity...
...
pre-requisites
Real-time storage replication service to duplicate the storage.
"
Anyway you can open a bugzilla request to ask for confirmation.
HIH,
Gianluca
