Hi chandan,

take a look at drbd9, this will probably solve your request.

https://github.com/LINBIT

Cinder driver is merged upstream (again): https://review.openstack.org/#/c/140451

nova driver is pending and waiting for approval (still -1): https://review.openstack.org/#/c/134153:

Did this help you? manfred

You can either make your controller redundant with drbd or you can run two controller nodes at the same time using a MySQL galera cluster, haproxy and load balance your controllers.

Best regards
