Hi all,
in the blueprint for Havana there were referrals for a possible implementation of something that would trigger Evacuate APIs in case of a node failure, sort of a vmware-ha like functionality.
Some people with legacy tenant applications are considering Openstack + vSphere just for this and sounds so lame to me...
Anyone with an update about this?
Hi,
Just to share, I've sort of made a work-around for the automatic failover of the instance, using a third party monitoring tool like Nagios. In our case our instances are all boot from volume, so it is a bit easier. When Nagios detects that a compute node is down, it triggers a script to update the host field of the instance in mysql and then do a hard-reboot to recreate the xml file.
Hi, 2 Controllers on active-passive setup , 8 Compute node (7 active-1passive), 3 ceph node. When you do nova service-list only 7 of the compute nodes are up, so that nova-scheduler will only use these nodes when launching the instance. The 8th node will only start when any of the compute node dies.
