Hi, We wish to add Active/Active High Availability to: 1] HPE 3par driver - cinder/cinder/volume/drivers/hpe/hpe_3par_common.py 2] Nimble driver - cinder/cinder/volume/drivers/hpe/nimble.py Checked documentation at https://docs.openstack.org/cinder/latest/contributor/high_availability.html https://docs.openstack.org/cinder/latest/contributor/high_availability.html#cinder-volume https://docs.openstack.org/cinder/latest/contributor/high_availability.html#enabling-active-active-on-drivers Summary of steps: 1] In driver code, set SUPPORTS_ACTIVE_ACTIVE = True 2] Split the method failover_host() into two methods: failover() and failover_completed() 3] In cinder.conf, specify cluster name in [DEFAULT] section cluster = <cluster_name> 4] Configure atleast two nodes in HA and perform testing Is this sufficient or anything else required ? Note: For Nimble driver, replication feature is not yet added. So can the above step 2 be skipped? Appreciate any suggestions / pointers. Regards, Raghavendra Tilay. -------------- next part -------------- An HTML attachment was scrubbed...
