Re: [Openstack] HA Compute & Instance Evacuation

Take this with a grain of salt because we're using the original version before the project moved under the Big Tent and I'm not sure how much it's evolved since then. I assume the basic functions are the same though. You're correct; Corosync and Pacemaker are used to determine if a compute node

Yes from Mitaka onward the snapshot happens at the RBD level which is fast. It's the flattening and uploading of the image to glance that's the major pain point. Still it's worlds better than the qemu snapshots to the local disk prior to Mitaka. John Petrini Platforms Engineer // *CoreDial
