Date Thu, 03 Aug 2017 09:54:00 GMT


ASF subversion and git services commented on CLOUDSTACK-9782:

Commit 98dc4eb96a3db1bd02f7ea7dab284f0d76b9dfb5 in cloudstack's branch refs/heads/master from
[;h=98dc4eb ]

CLOUDSTACK-9782: New Background Polling Task Manager (#2218)

CloudStack has several background polling tasks that are spread across
the codebase, the aim of this work is to provide a single manager to
handle submission, execution and handling of background tasks. With
the framework implemented, existing oobm background task has been
refactored to use this manager.

> 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 implementation specific for hypervisor that can
use additional mechanism such as OOBM (ipmi based power management) to reliably investigate,
recover and fencing a host. This feature can handle scenarios associated with server crash
issues and reliable fencing of hosts and HA of VM.
