Subject [DISCUSS][FS] Host HA for CloudStack
Date Thu, 16 Feb 2017 11:18:24 GMT
All,


I would like to start discussion on a new feature - Host HA for CloudStack.

CloudStack lacks a way to reliably fence a host, the idea of the host-ha feature is to provide
a general purpose HA framework and HA provider implementation specific for hypervisor that
can use additional mechanism such as OOBM (ipmi based power management) to reliably investigate,
recover and fence a host. This feature can handle scenarios associated with server crash issues
and reliable fencing of hosts and HA of VM. The first version will have HA provider implementation
for KVM (and for simulator to test the framework implementation, and write marvin tests that
can validate the feature on Travis and others).


Please have a look at the FS here:

Looking forward to your comments and questions.


Regards.
